6 FAQs about [How to replace the compensation capacitor steps]

What is the purpose of a compensation capacitor?

Objective of compensation is to achieve stable operation when negative feedback is applied around the op amp. Miller - Use of a capacitor feeding back around a high-gain, inverting stage. Miller capacitor only Miller capacitor with an unity-gain buffer to block the forward path through the compensation capacitor. Can eliminate the RHP zero.

Why do op amps need a compensation capacitor?

In addition, a better understanding of the internals of the op amp is achieved. The minor-loop feedback path created by the compensation capacitor (or the compensation network) allows the frequency response of the op-amp transfer function to be easily shaped.

How does a compensation capacitor affect frequency?

It is observed that as the size of the compensation capacitor is increased, the low-frequency pole location ω1 decreases in frequency, and the high-frequency pole ω2 increases in frequency. The poles appear to “split” in frequency.

Which capacitance should be used in a compensator design?

It should be noted here that the value of the capacitance used in the compensator design must be the small signal value. Ceramic capacitors lose some portion of their capacitance as their biasing voltage increases. The MLCC capacitors which are used in this example have 22μF nominal capacitance.

How to determine a compensator type?

The compensation type is determined by the location of zero crossover frequency and characteristics of the output capacitor as shown in Table 1. Step 5 - Determine the desired location of the poles and zeros of the selected compensator (this will be explained for each type of compensator).

How can a large effective capacitance be created with a smaller capacitor?

Since the pole ratio needs to be very large, CC gets very large ! Thus, a large effective capacitance can be created with a much smaller capacitor if a capacitor bridges two nodes with a large inverting gain !! ZIN =? Compensation capacitance reduced by approximately the gain of the second stage!
