The feedback capacitance of an inverting amplifier is 10 pF. What is the Miller capacitance at the input if the gain of the amplifier is -120?
Question
Solution 1
The Miller effect states that the input capacitance of an amplifier is increased due to the amplification of the signal. The Miller capacitance (Cm) can be calculated using the formula:
Cm = Cf * (1 - A)
where: Cf is the feedback capacitance, A is the gain of the amplifier.
