摘要： Five circuit topologies of Voltage-Controlled Oscillators with Single Inductor (VCO-1L) are proposed. They offer lower power consumption, higher output amplitude, broader tuning range, cleaner s-rum and higher frequency stability seen as lower phase-noise. Most of the achievements are based on the development of active pull-down control circuitries of the timing and active charge dissipation in the transistors. The applications of the present invention are of critical importance for wireless communication systems not allowing any limitations in the frequency range. Among them are base stations and mobile terminals mobile phones, GSM, PCS/DCS, W-CDMA etc., as well BlueTooth, Wireless LAN, Automotive and ISM band etc. The advanced performance of the circuits is based on important architectural specifics and proven by simulation on advanced CMOS process. The architectures are not limited to use on CMOS; they can be efficiently used in any semiconductor process where complimentary polarity transistors are available, for example BiCMOS, SiGe/BiCMOS, GaAs etc.

摘要： A switched mode power supply provides a reduction of switching losses and increased efficiency. The switched mode power supply includes a first switch coupled to an input terminal configured to receive an input voltage, a second switch, an inductor and an output capacitor. The first switch and the second switch are coupled together at a node, the inductor is coupled between the node and an output terminal, and the output capacitor is coupled to the output terminal. The switched mode power supply further includes a transformer coupled between a control input of the first switch and the node and a pulse generator connected to a control input of the second switch. Further, the transformer includes at most two windings, in particular a primary winding and a secondary winding which are not directly connected to each other.

A multivibrator circuit comprises an operating voltage source, first and second nonlinear amplifier components, each comprising a first and a second main electrode and a control electrode, wherein the first main electrode of the second amplifier component is connected to control the control electrode of the first amplifier component, and the first main electrode of the first amplifier component is connected to control the control electrode of the second amplifier component. A capacitor is connected between the second main electrode of the first and second amplifier components. First and second resistors connect the first main electrode of the first and second amplifier components to a first potential of the operating voltage source. A pull-down circuit is connected between the second main electrodes of the first and second amplifier components and a second potential of the operating voltage source. The pull-down circuit comprises third and fourth amplifier components, acting as active pull-down components which are cross-connected such that they are alternately in conducting and nonconducting states due to forced control by the states of the first and second amplifier components.

摘要： In a voltage-controlled LC oscillator, a series LC resonance circuit is connected between two transistor amplifying stages which provide low impedance input and output circuits for the LC circuit. The collector of the first transistor stage is connected through a coil to the operating voltage. The emitter of the second transistor stage is connected to the reference voltage through a coil. This will result in narrowband transistor stages and significant advantages in the power consumption and other characteristics of the oscillator.
