In this paper, a high gain low voltage three stage Opamp has been discussed. We used a negative resistance load for the amplifier stages without compromising on dc latch-up issues. Nested miller compensation for three stages has been discussed and presented systematic producer to approach the optimal specification space. The proposed circuit is implemented in 65nm CMOS technology and simulated with Spectre. Simulation results shows that the proposed circuit offers 102dBdc gain, 1-MHz unity gain bandwidth under 0.5pF load capacitance. Step response agreed with the frequency response. The circuit consumes \pmb{346\mu\mathrm{W}} from 1V supply and occupying \pmb{3000\mu \mathrm{m}^{2}} silicon area. © 2018 IEEE.
