=> VO = {(1/j2ΠfC)/[Ro + (1/ j2πfC)] } × AVid = AVid / [1+ j2πfRoC]. 2. Compute the break frequency of an op-amp, if the output resistance=10kΩ and capacitor connected to the output =0.1µF.
A. 159.2Hz
B. 6.28Hz
C. 318.4Hz
D. 1000Hz
Answer:A
=> VO = {(1/j2ΠfC)/[Ro + (1/ j2πfC)] } × AVid = AVid / [1+ j2πfRoC]. 2. Compute the break frequency of an op-amp, if the output resistance=10kΩ and capacitor connected to the output =0.1µF.
A. 159.2Hz B. 6.28Hz C. 318.4Hz D. 1000Hz
Explanation: Break frequency of the op-amp is given as fo = 1/(2πRoC)= 1/ (2π×10kΩ×0.1µF) = 1/ (6.28×10-3) = 159.2Hz. 3. The open loop voltage gain as a function of frequency is defined as
