What is a CC capacitor?

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.

What is a good size capacitor for a low frequency circuit?

Reasonable sizes for the lengths are usually 1.5 to 10 times of the minimum length (while digital circuits usually use the minimum). For low-frequency applications, the gain is one of the most critical parameters. Note that compensation capacitor Cc can be treated open at low frequency.

What is internal compensation technique in op-amp IC?

In the internal compensation technique, a small feedback capacitor is connected inside of the op-amp IC between the second stages Common emitter transistor. For example, the below image is the internal diagram of popular op-amp LM358. The Cc capacitor is connected across the Q5 and Q10. It is the compensation Capacitor (Cc).

How does a capacitor work?

This capacitor creates a pole that is set at a frequency low enough to reduce the gain to one (0 dB) at or just below the frequency where the pole next highest in frequency is located. The result is a phase margin of ≈ 45°, depending on the proximity of still higher poles.
