摘要： Double sided versions of several power transistor types are devices that are already known in the literature. Devices built in this configuration are generally required to have a separate driver circuit to control the front and rear control electrodes and provide the gate or base voltage and/or currents for the power switch. This is because there may be of the order of 1000V potential-difference between the frontside and rearside potentials when the transistor is in the off condition—and a single integrated circuit cannot generally sustain this within a single package. The NPN configuration is preferred in this case to benefit from electron conduction for the main power path between the emitters. However, problems arising when using a P-type wafer. The present invention seeks to avoid the use of P-type wafers while still getting the higher conduction performance of NPN operation.

摘要： A power supply device includes a power switch that is switched according to a gate voltage. A sense resistor receives a switch current that flows through the power switch to develop a sense voltage. A peak of a primary-side current is detected from the sense voltage. The gate driver has a pair of switches for generating the gate voltage in

摘要： A sensing circuit configured to activate a controller is disclosed. The circuit comprises a first transistor configured to output an activation signal to the controller and a plurality of switches in connection with a base of the transistor. Each of the switches is connected to an identifying resistor. A first output node and a second output node are in communication with the base of the transistor and each of the switches. The first output node and the second output node are separated across an additional identifying resistor. The first output node and the second output node are configured to output a characteristic voltage corresponding a ratio of each of the identifying resistors in response to an input received by one or more of the plurality of switches.

摘要： A damping circuit having an input terminal and an output terminal is described. The damping circuit comprises a driver having an input and an output; an RC circuit coupled between the input terminal and the output; and a resistor coupled between the output and the output terminal, wherein the RC circuit delays passing a signal from the output terminal to the input terminal and a low impedance associated with the driver generally reduces ringing.

摘要： The present application teaches, inter alia, methods and circuits for operating a B-TRAN (double-base bidirectional bipolar junction transistor). Exemplary base drive circuits provide high-impedance drive to the base contact region on the side of the device instantaneously operating as the collector. (The B TRAN is controlled by applied voltage rather than applied current.) Current signals operate preferred implementations of drive circuits to provide diode-mode turn-on and pre-turnoff operation, as well as a hard ON state with low voltage drop (the “transistor-ON” state). In some preferred embodiments, self-synchronizing rectifier circuits provide adjustable low voltage for gate drive circuits. In some preferred embodiments, the base drive voltage used to drive the c-base region (on the collector side) is varied while base current at that terminal is monitored, so no more base current than necessary is applied. This solves the difficult challenge of optimizing base drive in a B-TRAN.

摘要： Apparatus and methods to increase the range of a signal processing circuit. A system uses floating bias circuits coupled to a signal processing circuit to increase the range of power supplies that can be used with the signal processing circuit, while maintaining the components of the signal processing circuit within a breakdown voltage threshold. As the voltage level of the data signal varies, the voltage level of the floating bias circuits varies as well.
