WebThis type of amplifier uses a transformer to couple the output signal to its load. 10 AC Operating Characteristics The value of vce (off) for a transformer-coupled class A amplifier is nearly twice the value of VCC. The maximum theoretical efficiency for this type of amplifier is 50. 11 Class B Amplifiers Contain two transistors. WebA Darlington pair behaves like a single transistor with a very high current gain. It has three leads (B, C and E) which are equivalent to the leads of a standard individual transistor. …

WebAn Amplifier circuit is one which strengthens the signal. The amplifier action and the important considerations for the practical circuit of transistor amplifier were also detailed in previous chapters. Let us now try to understand the classification of amplifiers. Amplifiers are classified according to many considerations.
