摘要： An Ethernet network is composed of one or more network infrastructure devices, such as a hubs, repeaters, switches or routers, which provides data interconnection and may provide operational power, or some part thereof, to remote network data terminal equipment such as a wireless access point, IP telephone, IP camera or network end station. Most Ethernet networks operate over a combination of the pairs in an unshielded twisted pair (UTP) or shielded twisted pair (STP) cable, or in some cases may operate over fiber optic cables. The individual links of Ethernet network, between the network infrastructure device and the Data Terminal Equipment (DTE) may be able to operate at one or more data rates such as 10 Mb/s, 100 Mb/s, 1 Gb/s, 2.5 Gb/s, 5 Gb/s and 10 Gb/s, or any combination thereof. The invention discloses an Ethernet Physical Layer (PHY) circuit, in combination with an Integrated Connector Module (ICM), which may reside inside the network equipment at either end of the Ethernet link. The combined PHY-ICM physical layer network device provides the appropriate encoding/decoding and signaling to operate over the specific network cable medium at the required data rate(s). The electrical and mechanical design of the combined PHY-ICM enables a modular approach such that during final assembly, the PHY-ICM can be optimized for operation over the appropriate data rate(s), whether it supports the provision of operational power between the network equipment, and if so at what power level, as well as other functionality. Furthermore, the PHY-ICM is designed to maintain a common electrical and mechanical footprint regardless of which of the features are included or excluded, to optimize the system cost for a specific maximum data rate, as well as minimize any re-engineering necessary on the part of the network equipment designer.

摘要： A power supply circuit with low noise and low power consumption and a battery device using the power supply circuit. If a voltage VDD is higher than a prescribed voltage, a charge pump circuit 140A is operated in “½ mode” (a step-down ratio of “2”), steps down the voltage VDD, and outputs an intermediate voltage VCPO. Since the voltage VDD is stepped down, the intermediate voltage VCPO being input into a first LDO 135 is about half the case where no step-down is carried out, and the power being consumed in a MOS transistor Q11 (FIG. 3) of the first LDO 135 is greatly reduced. Therefore, the increase in power consumption of the first LDO 135 due to a voltage increase in the voltage VDD can be suppressed. Also, since the heat sink of the first LDO 135 can be reduced in size or omitted by the suppression of power consumption, the size and weight of the device can be reduced.
摘要翻译：具有低噪声，低功耗的电源电路和使用电源电路的电池装置。如果电压VDD高于规定电压，则电荷泵电路140A以“1/2模式”（降压比“2”）运行，降压电压VDD，并输出中间电压VCPO。由于电压VDD被降低，输入到第一LDO 135的中间电压VCPO大约是不执行降压的情况的一半，并且在MOS晶体管Q11（图3）中消耗的功率第一LDO 135大大减少。因此，可以抑制由于电压VDD的电压上升引起的第一LDO 135的功耗的增加。此外，由于可以通过抑制功率消耗来减小第一LDO 135的散热器的尺寸或省略，所以可以减小装置的尺寸和重量。

摘要： An LDO regulator (10) produces an output voltage (Vout) by applying the output voltage to a feedback input (6) of a differential input stage (10A) and applying an output (3) of the differential input stage to a gate of a first follower transistor (MP4) having a source coupled to an input (8) of a class AB output stage (10C) which generates the output voltage. Demanded load current is supplied by the output voltage during a dip in its value to a gate of a second follower transistor (MP5) having a gate coupled to the output of the input stage to decrease current in a current mirror (MN5,6) having an output coupled to a current source (I1) and a gate of an amplifying transistor (MN7). This causes the current source to rapidly turn on the amplifying transistor to cause it to rapidly turn on a cascode transistor (MN3), causing it to turn on a pass transistor (MP3) of the output stage.

摘要： A regulator to provide an output voltage of a constant level at an output node. In an embodiment, the regulator contains a pass transistor to provide a conductive path between a pair of terminals, with the resistance offered by the path being determined by a control voltage on a third terminal of the pass transistor and the conductive path coupling a first reference potential (e.g., power supply) to the output node. An amplifier generates the control voltage based on a difference of a reference voltage and a voltage proportionate to the output voltage. A control unit turns on a current source when the voltage at the output node is below the desired constant level and turns on a current sink when voltage at said output node is above the constant level, to quickly correct for any variations in the output voltage due to load changes.

摘要： The invention relates to smoothing a consumer electrical circuit supplied by a controllable current sink connected in parallel to the consumer. For this purpose, measuring voltage proportional to a load current supplied to the consumer is derived therefrom. A pick value measuring device makes it possible to determine a maximum value thereof. The difference between the maximum value and measuring voltage makes it possible to control the voltage-controlled current sink in such a way that the sum of a compensation current supplied by the current sink and the load current which runs by the consumer is substantially constant.

摘要： This device determines a quantity corresponding to a linear function of a voltage to be detected, and includes a circuit for charging with a determined time constant a capacitor, and a microcontroller. The microcontroller compares the voltage across the capacitor to a predetermined threshold and then resets the voltage across the capacitor. A counter counts the time duration between the end of a capacitor reset and the time when it reaches the predetermined threshold and calculates the inverse of said duration. This data can then be used to signal the end of a process, such as the proper charging of rechargeable batteries.

摘要： A process and apparatus for resistance-welding produce a welding current which pulsates in periodic half-waves, in particular an alternating current. The, welding current is generated from a primary alternating voltage which is chopped n times (n>1) in each half-wave and pulse width modulated in order to regulate the welding current. A regulator is provided and has a storage device containing the current nominal values for each chopping interval, corresponding to the welding current form, for comparison with each actual current value determined in each chopping interval.

摘要： A pulse welding apparatus using a pulse discharge such as a pulse arc welding apparatus and a short-circuit transfer arc welding apparatus. A pulse current waveform control circuit, which controls the pulse arc current so that a desired pulse arc current is supplied to the arc welding power supply for outputting the pulse arc current to the welding load unit, is constructed such that the optimum welding operation may be performed without having to adjust circuit components and modify circuit design. The pulse current waveform control circuit is in the form of a microcomputerized digital circuit which operates under a program to provide a desired pulse arc current. A modification of the program can provide any desired pulse arc currents without changing circuits. The optimum welding current waveform parameters or a target arc length signal is learned in the first welding stage and stored into a memory. An arc length feedback control or a current waveform control is performed under the control of program on the basis of the optimum welding current waveform parameters or the target arc length signal so as to control the faulty separation of globules when magnetic blow occurs and so as to reduce the variation of arc length due to external disturbances occurring at the welding torch so that improved welding quality is ensured under various environments.

摘要： An invertor controlled D.C. arc welder of consumable electrode type which is arranged to rectify an a.c. power from a commercial power supply, convert it into a high frequency a.c. power by an invertor, rectify it again to obtain a d.c. power output for welding and stabilize the output voltage by feedback control of the invertor based upon the output voltage and provided with means for discriminating shorting and arcing periods of its welding load from the output voltage and additionally controlling the invertor based upon a resultant discrimination signal to raise the output voltage during the early time of the arcing period, thereby preventing defective welding due to insufficient output current. This invention is especially, effective for supplementing such insufficient output current as an aftereffect of insufficient output power during the shortening period in such welder which is provided with means for reducing the output voltage during the shortening period to prevent generation of undesirable spattering.
