Function Generator Based on Circuit Simulation Method

Abstract

The function generator has a wide range of applications, mainly used in various production testing and scientific and technological fields such as chemical industry, communication engineering, industrial control, military, aerospace and so on. The function calculator based on the circuit simulation method can be quickly adjusted according to the output frequency, amplitude, and phase under the premise of ensuring accuracy. This article uses Falstad for circuit simulation and TinkerCad for circuit modeling. From the circuit scheme selection, analysis, optimization and other links, all use electronic simulation, without using any physical electronic components. At the same time, the theoretical equation and the simulated function curve are compared. Through comparison, it is found that the overall trend of the simulated curve is similar to the theoretical value, but the maximum amplitude appears later and smaller than the theoretical value.
