Which consequence results when parasitic capacitance forms in CMOS amplifiers?

A)Decreased amplifier gain at high frequencies
B)Increased power supply ripple rejection
C)Improved amplifier phase margin stability
D)Reduced input bias current requirement

💡 Explanation

Increased parasitic capacitance introduces unwanted impedance, therefore causing a signal path for high frequencies, because this results in high-frequency gain reduction arising from capacitive reactance bypassing the intended amplification; rather than phase changes or bias shifts.
