Compensating Network in Op Amp:
The main purpose of a Compensating Network in Op Amp is to improve the performance of an op-amp circuit over the desired frequency range by controlling its gain and phase shift. First …
Placement of compensation capacitor
Normally, the compensation capacitor is placed from the output of the first stage to the output of the second stage (and thus it envelopes the VAS stage). ==> The slew rate depends upon the …
Operational amplifier stability compensation methods for …
To remove this instability and work with higher capacitive loads, many compensation methods exist, and this application note examines some of them. By adding zeroes and poles to the …
LECTURE 120 – COMPENSATION OF OP AMPS
Objective of compensation is to achieve stable operation when negative feedback is applied around the op amp. Types of Compensation 1. Miller - Use of a capacitor feeding back around …
Frequency Compensation of Op-amp and its types
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 …
