← ScienceWhich risk increases near the saturation drain voltage limit of a field effect transistor?
A)Increased electron-hole recombination rate
B)Channel length modulation effects✓
C)Reduced gate oxide tunneling current
D)Decreased substrate doping concentration
💡 Explanation
Channel length modulation increases because the depletion region extends further towards the source, effectively shortening the channel; therefore, the transistor's output impedance decreases rather than recombination increasing because drain voltage has exceeded limits.
