Frequency compensation
In electronics engineering, frequency compensation is a technique used in amplifiers, and especially in amplifiers employing negative feedback usually has two primary goals: To avoid the unintentional creation of positive feedback, which will cause the amplifier to oscillate, and to control overshoot and ringing in the amplifier''s step response is also used extensively to

Increase in compensation capacitor for op-amp
I am currently learning to design an op-amp, and understand that using compensation capacitors help to maintain stability of the op-amp. Currently, my compensation capacitor has a value around 10 pf. I would like to know what will happen if I increase this value to 30 pf, how is the gain bandwidth product affected? Thank you.

What are the types of compensation capacitors?
Compensation capacitors are divided into two type families (A and B) in accordance with IEC 61048 A2. • Type A capacitors are defined as: "Self-healing parallel capacitors; without an (overpressure) break-action mechanism in the event of failure". They are referred to as unsecured capacitors.
Can bidirectional Capacitor multipliers provide on-chip compensation and fast transient mechanisms?

The bidirectional current mode capacitor multipli r technique can effectively move the crossover frequency toward to the origin in the start-up pe-riod for a smoothly rising
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.
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.
