Abstract
The emitter follower configuration, which is usually driven by another amplifier stage, is discussed. Together, the preceding and emitter follower stages are modified to provide constant-output DC levels. A design method to stabilize these voltage levels is presented. Several practical circuits are illustrated. Typical results show the output DC voltage to have a temperature coefficient of only 0.6-0.7 mV/°C. This constant bias maximizes transistor performance, increases signal headroom, and improves circuit stability
