An engineer increases gate oxide capacitance in a MOSFET; which outcome is most likely?

A)Reduced channel carrier mobility results
B)Increased subthreshold swing degrades performance
C)Lower drain-induced barrier lowering occurs
D)Higher transconductance improves amplifier gain

💡 Explanation

A larger gate oxide capacitance increases the gate's control over the channel, because it allows for a greater change in channel charge with respect to gate voltage, resulting in higher transconductance, therefore amplifier gain improves rather than other parameters being directly affected.
