基于人工智能算法的单级全差分折叠式共源共栅运算放大器的多目标设计方法
Multi-Objective Design Method for Single-Stage Fully Differential Folded Cascode Operational Amplifiers Based on the Artificial Intelligence Algorithm
摘要
Abstract
With the advancement of integrated circuit manufacturing technology,analog integrated circuit design fac-es the challenge of trade-offs between performance metrics such as power consumption and gain.Traditional design meth-ods,reliant on approximate equations and iterative refinement,are inefficient.This paper presents an artificial intelligence algorithm-based multi-objective design strategy for the design of a single-stage fully differential folded cascode operational amplifier.This method employs a neural network model to characterize the mapping relationship between design parame-ters and eight performance metrics,and sets the target performance for the operational amplifier to achieve through fitness functions and constraint conditions,then utilizes particle swarm optimization(PSO)algorithm to search for the optimal fit-ness.Experimental results show that multiple metrics exceed design targets,with a maximum voltage gain of 65 dB and a phase margin of 74°.Using this method,we can quickly and accurately obtain operational amplifier parameters that meet de-sign specifications.Compared to manual calculations,this method reduces the running time to merely 906 seconds,signifi-cantly improving the design efficiency.It can be applied to more large-scale circuit designs in the future.关键词
