B. Use resistor
C. Use capacitor
D. Use transistor
Answer:A
Explanation: The gain of the op-amp roll-off due to the presence of capacitive component, in the equivalent circuit of op-amp. The frequency increases as the reactance of the component decreases. 2. What remedy can be followed to maintain the operating frequency in the op-amps?
A. Use LC circuit B. Use resistor C. Use capacitor D. Use transistor
Explanation: Capacitors are used in the high frequency model of the op-amp at the output terminal to maintain or control the frequency. 3. How does the physical characteristic of semiconductor account for the increase in frequency of op-amps?
