6 FAQs about [Phase compensation capacitor drawing]

How does phase compensation work?

In this system, the phase compensation is configured by connecting resistor RITH and capacitor CITH in series with the output of the error amplifier . Rea represents the output resistance of the error amplifier, Vref is the reference voltage, and VFB is the feedback reference voltage (Figure 1). Figure 1. Phase compensation circuit diagram 2.

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.

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.

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.

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.

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.
