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 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 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.
What is a Miller capacitor?
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. Miller with a nulling resistor.
Can compensation capacitor CC be treated open at low frequency?
Note that compensation capacitor Cc can be treated open at low frequency. It should be noted again that the hand calculation using the approximate equations above is of only moderate accuracy, especially the output resistance calculation on rds. Therefore, later they should be verified by simulation by SPICE/SPECTRE.
