Overlap capacitance
WebQuestion: Prob la: A common problem in amplifying weak signals is that the overlap capacitance of the amplifier (For example: the capacitance between drain and gate of the input device) is amplified by the “miller" effect and is seen as a load to the driver, often degrading the frequency response of the circuit.
