Webbthermal runaway, particularly with reactive loads, unless suitable protective circuitry is employed. These requirements have combined to increase the complexity of the circuit arrangement, and a well designed low-distortion class B power amplifier is no longer a simple or inexpensive thing to construct. Wireless World, April 1969 Webb5 dec. 2016 · Thermal runaway in BJT-based push-pull Class AB amplifiers occurs due to the negative temperature of the base-emitter voltage V BE. The V BE temperature coefficient is typically about -2 mV/°C. The worst bias arrangements for Class AB amplifiers with respect to thermal runaway are those that use bias voltages that are …
