← TechnologyWhich operational consequence arises when a MOSFET, used in an audio amplifier operating at 20kHz, experiences channel length modulation?
A)Increased harmonic distortion✓
B)Reduced power dissipation
C)Improved signal linearity
D)Decreased switching speed
💡 Explanation
Increased harmonic distortion occurs because channel length modulation causes the effective channel length to vary with drain voltage, therefore altering the MOSFET's output current non-linearly, rather than maintaining a constant gain.
