Design Optimization Methodology for CMOS Operational Amplifier Using NSGAII
Subscribe/Renew Journal
This paper focuses on the synthesis and design of CMOS operational amplifiers (op amps) using novel multi objective algorithm. The synthesis of CMOS op-amps can be translated into a multiple-objective optimization task, in which a large number of specifications have to be taken intoaccount, i.e., area, power consumption, slew rate and gain-bandwidth. A multi-objective algorithm called elitist non-dominated orting genetic algorithm (NSGA-II) is applied to search for multiple optimal solutions, which includes transistor sizes, bias currents and compensating capacitance values. The knowledge of this helps the designer to compare and choose a compromised optimal solution for automating the operational amplifier design. The proposed methodology has the ability to generate in short times constraint satisfying solutions The algorithm is implemented in C programming language and PSICE is used to evaluate the required circuit parameters The simulation results confirms the efficiency of the NSGA-II algorithm in determining the device sizes.
