← TechnologyIn a MOSFET-based power amplifier under high-frequency operation, which consequence arises from increased gate-drain capacitance?
A)Miller effect reduces gain✓
B)Increased drain-source on-resistance
C)Decreased switching power dissipation
D)Enhanced channel length modulation effects
💡 Explanation
The Miller effect is amplified feedback due to gate-drain capacitance because increased frequency causes increased capacitive reactance, therefore lowering amplifier gain, rather than other effects which correlate to channel length or conduction.
