I have an exam tomorrow and I have a theoretical question. Just have Miller effect common source (FET) / common emitter (BJT)? Or common drain (FET) / common collector (BJT) also have? Is there some kind of circuit I did not mention that has Miller effect?
Miller effect only occurs on amplifiers. Inverting amplifiers to be specific.
Common collector transistor circuit has a gain of 1, ie it does not amplify. In this case, Cgd or Cbc is a simple capacitor, and it is not multiplied by Miller effect.
Common emitter amplifier circuit has negative gain, and thus Miller effect applies to Cbc/Cgd.
