Explanation: Two types of plots can be obtained using Bode plot. They are magnitude versus frequency and phase angle versus frequency plots. 7. What happens when the operating frequency of an op-amp increase?
A. Gain of the amplifier decrease
B. Phase shift between output and input signal decrease
C. Gain and phase shift of amplifier decreases.
D. None of the mentioned.
Answer:A
Explanation: Two types of plots can be obtained using Bode plot. They are magnitude versus frequency and phase angle versus frequency plots. 7. What happens when the operating frequency of an op-amp increase?
A. Gain of the amplifier decrease B. Phase shift between output and input signal decrease C. Gain and phase shift of amplifier decreases. D. None of the mentioned.
Explanation: When the operating frequency is increased the gain of the amplifier decrease. As it is linearly related to frequency, the phase shift is logarithmically related to frequency. 8. Which of the following causes change in gain and phase shift?
