WebDec 18, 2009 · The common-collector/emitter-follower amplifier can amplify AC-couple analog signals linearly if the transistor's base is biased to a quiescent value of about half the supply voltage. This permits maximum signal swings without distortion due to clipping. WebThe emitter-follower amplifier is also known as a common collector amplifier. It is a single-stage bipolar junction transistor, or BJT, often used as a voltage buffer. This is because it can be used for high input and low output impedance. It can help match impedance in circuits. earth and sun axis
