Hi, I want to simulate this schematic which is a folded cascode opamp with 2 stages for a higher gain and a Miller capacitor, but I don't understand what...
Design of self-biased folded cascode CMOS op-amp using PSO algorithm for low-power applicationsIn this paper, a new dual-output second generation current conveyor (DO-CCII) circuit based-on resistive compensation technique is proposed. The resistive compensation technique is very simple and powerful...
This paper presents a new technique to improve CMOS recycling folded cascode (RFC) operational amplifier (Op-Amp). Our modification is based on shorting two nodes in the conventional RFC circuit. It causes that the seen resistance from the created new node be half of the conventional RFC counte...
