← ScienceWhich 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.
