| Abstract: | Filter is an element which can choose the frequency.It can pass the specifically frequency and makes the others attenua- tion.This paper introduces the development and the type of the simulation filter.By the design of the simulation filter,and analyse and em- ulation the resistance-capactiance＇s characteristic with the temperature＇s change of the active low pass filter,presenting how to solve the influence about frequency response and sensitivity causing by the resistance-capactiance temperature excursion. |
