Internal and external op-amp compensation: a control-centric tutorial

Frequency compensation of two-stage integrated-circuit operational amplifiers is normally accomplished with a capacitor around the second stage.

6 FAQs about [Compensation capacitor technical standards]

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.

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.

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.

What is a series capacitor?

The series capacitor units and banks are usually intended for high-voltage power systems. This standard is applicable to the complete voltage range. This standard does not apply to capacitors of the self-healing metallized dielectric type. The following capacitors, even if connected in series with a circuit, are excluded from this standard:

Which capacitor is used to compensate a dead zone?

Compensation of the output-buffer dead-zone region is provided by Q18 and Q19. Output-current limiting and short-circuit protection is imple-mented by Q15 and Q21–Q25. And of course, the frequency compensation is accomplished by the 30 pF capacitor around Q16 and Q17, as discussed in Section II. Fig. 45.
