Explanation: The open loop voltage gain as a function of frequency is defined as ratio of output voltage to the difference of input voltages. 4. Which among the following factor remain fixed for an op-amp?
A. Open loop voltage gain
B. Gain of the op-amp
C. Operating frequency
D. Break frequency of the op-amp
Answer:A
Explanation: The open loop voltage gain as a function of frequency is defined as ratio of output voltage to the difference of input voltages. 4. Which among the following factor remain fixed for an op-amp?
A. Open loop voltage gain B. Gain of the op-amp C. Operating frequency D. Break frequency of the op-amp
Explanation: Break frequency fo depends on the value of capacitors and on output resistance. Therefore, fo is fixed for any op-amp. 5. Find the gain magnitude and phase angle of the op-amp using the specifications:
