ABSTRACT:
The systems and methods described herein provide for composite transistor circuit having a bipolar transistor and a compensation unit. The compensation unit can be configured to stabilize the DC biasing point of the bipolar transistor. The compensation unit can compensate for the self-heating effect in the bipolar transistor and/or improve the linear performance of the bipolar transistor. The compensation unit can include a nonlinear resistor in series with a switch and can be configured to increase the base current into the bipolar transistor as the output voltage of the circuit increases.
