In this paper, a technique that improves the phase response of the folded cascode Operational Transconductance Amplifiers (OTAs) is presented. It is shown that with two extra connections the effects of the high frequency poles are minimized and the parasitic oscillations, due to limited phase margin, are further reduced. Therefore, without additional components, the phase margin of the classical folded cascode OTA is improved and the capacitive loaded amplifier settles faster.
