Regulation circuit for field effect transistor (FET) has first and second switching configurations for respectively maintaining and regulating source voltage of FET

摘要

A connecting channel (K) is provided between the source (S6) and drain (D6) of a FET (T6) whose channel resistance is adjustable. A first switching configuration maintains the source voltage at a constant voltage level if the input channel voltage, Kin, is greater than or equal to zero and the output channel voltage, Kout, is less than or equal to 1.5 volts. A second switching configuration regulates the source voltage due to a variation in the input and output channel voltages.
