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.
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.
That means a capacitor is connected in the feedback loop to compensate the op-amp frequency response. The miller compensation circuit is shown below. In this technique, a capacitor is connected to the feedback with a resistor across the output.
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.
The Cc capacitor is connected across the Q5 and Q10. It is the compensation Capacitor (Cc). This compensation capacitor improves the stability of the amplifier and as well as prevent the oscillation and ringing effect across the output.
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!
