Class B amplifier has automatic bias
Class B amplifier has automatic bias
21.06.2017 · Circuits
B amplifiers are prone to crossover distortion, which occurs in the output stage in which conduction transfers from one transistor to the other. To prevent crossover distortion, a bias current must flow in both transistors simultaneously. The bias current prevents both transistors from turning off in the transition region. Classic bias circuits keep a constant dc polarization voltage between the bases of the two transistors...
