6 FAQs about [Three types of compensation of capacitors]

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.

Do op-amps have internal compensation capacitors?

The internally Compensating Network in Op Amp use a metal oxide capacitor built within the IC. The circuit configuration is given in Fig. 35.3. Although this works well, internal compensation does not allow us any control over the op-amp frequency response. The 301 and 709 op-amps have no internal frequency compensation capacitor.

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.

How does a capacitor compensate op-amp frequency response?

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.

What is a Miller capacitor?

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. Similar to Miller but with an added series resistance to gain control over the RHP zero.
