A Hybrid Folded Cascode OP Amp with Positive Feedback And DSB Circuit

Abstract

A novel high-speed folded-cascode OP Amp with positive feedback and a dynamic switching bias circuit, which increases the speed and lower the power dissipation has been proposed . The proposed Op-Amp was designed in a standard 0.18µm CMOS technology and simulation is performed using tanner EDA tool. Simulation results show a considerable increase in speed, increased output voltage swing and low power consumption for the presented Op-Amp. This proposed circuit overcomes some drawbacks of the conventional circuit in which only positive feedback is used.
