How is the Miller effect used in frequency modulation? How is the capacitance varied with input though the gain of the amplifier is constant?
Can you explain how the Miller effect is used in frequency modulation?
The Miller effect is a phenomenon in which the effective capacitance at a node in a circuit is increased due to the presence of a grounded capacitor between the input and output of an amplifier. This effect is used in frequency modulation by varying the capacitance with input while the gain of the amplifier is constant.
