[amp_mcq option1=”Low output capacitance” option2=”High on resistance” option3=”High output capacitance” option4=”Input capacitance does not affect speed of the gate” correct=”option1″]
The correct answer is: A. Low output capacitance.
The output capacitance of a gate is the capacitance that is charged and discharged when the gate is turned on or off. The higher the output capacitance, the longer it takes for the gate to switch states. Therefore, a fast gate can be built by keeping the output capacitance low.
Option B is incorrect because a high on resistance will slow down the gate. When a gate is turned on, the current flows through the on resistance. The higher the on resistance, the longer it takes for the gate to turn on.
Option C is incorrect because a high output capacitance will slow down the gate. The higher the output capacitance, the longer it takes for the gate to switch states.
Option D is incorrect because input capacitance does affect the speed of the gate. The higher the input capacitance, the longer it takes for the gate to respond to an input signal.
