Abstract
This paper presents a new method to decrease the distance of the poles situated in two different nodes of an amplifier by using a positive feedback capacitor. The method can be used in various situations such as shaping the frequency response to help compensating of an OTA or suppressing the effect of some poles in a fully differential multistage amplifier to increase its GBW. The technique seems to be functional with any type of two stage and multistage op-amps and is usually very easy to implement.
