Explanation: Op-amp using external components like resistor and capacitor to form the compensating network are sometimes called tailored frequency response op-amps because the user has to provide the compensation if it is needed to tailor the response. 4. In the first generation op-amp 709c, the open loop bandwidth of gain versus frequency curve
A. Increases from the innermost compensated curve to the outermost
B. Decrease from the innermost compensated curve to the outermost
C. Increases from the outermost compensated curve to the innermost
D. Decreases from the outermost compensated curve to the innermost
Answer:A

A. Increases from the innermost compensated curve to the outermost B. Decrease from the innermost compensated curve to the outermost C. Increases from the outermost compensated curve to the innermost D. Decreases from the outermost compensated curve to the innermost
Explanation: The gain versus frequency curve of 709c decreases from the outermost compensated curve to the innermost. For example, if C1 =10pF, R1 = 0Ω and C2 = 3pF, the bandwidth ≅ 5kHz. While if C1 =5000pF, R1 =1.5Ω and C2= 200pF, the bandwidth will be 100Hz. 5. Which type of op-amp offer relatively broader open-loop bandwidth?
