Multi-Objective Learning Automata for Design and Optimization a Two-Stage CMOS Operational Amplifier

In this paper, we propose an efficient approach to design optimization of analog circuits that is based on the reinforcement learning method. In this work, Multi-Objective Learning Automata (MOLA) is used to design a two-stage CMOS operational amplifier (op-amp) in 0.25μm technology. The aim is optimizing power consumption and area so as to achieve minimum Total Optimality Index (TOI), as a new...

Operational Amplifier with Two-Stage Gain-Boost

In this paper we present a three-stage fully differential operational amplifier in 120nm digital CMOS. To reach high gain gain-boosted cascodes in the first stage are used. The gain-boost amplifiers are realized as two-stage amplifiers with self cascodes. A DC gain of 108dB and an unity-gain frequency of 1.06GHz are achieved at 1.2V supply. The operational amplifier is appropriate for supply vo...

Area-constrained Design of Differential Input Stage for a Two-stage Compensated Operational Amplifier

A new figure of merit under area constraints is proposed for designing optimum performance differential input stage of a two-stage compensated operational amplifier. Figure of Merit, FoM2 is defined that includes the three small signal performance parameters, namely input-referred noise, unitygain bandwidth and differential dc gain. Expressions for these parameters in terms of area assigned, ha...
