Research and optimization design of voltage divider biasing circuit based on PSpice

Abstract

Based on the practical characteristics of the basic course of electronic technology, a new method of optimizing the circuit by using the parameters scanning function of PSpice simulation technology is proposed, which is to perform basic transient scanning on the circuit to meet the basic functions of the amplifying circuit. After discovering the unreasonable technical parameters, the parameters of the circuit are scanned and modified. After correcting the incorrect parameters, the optimized analyze design module is used to optimize the circuit design. The optimal design process and simulation results of the voltage-divided bias amplifier circuit by this method are presented. The experimental results show that the optimal design of the amplifying circuit can not only meet the performance parameters required by the constraints and target conditions but also reduce the number of optimization iterations and simulation execution by adjusting the performance specifications of the circuit, thus improving efficiency and accuracy of the optimization design. At the same time, it also verifies the effectiveness and feasibility of optimizing the circuit and design through the simulation.
