| Abstract: | Based on the principle of switched-capacitor filter,a new method of designing programmable filter with MAX263 is put forward in this paper.This filter can be set in low-pass or high-pass mode.Besides,the cut-off frequency and gain can be controlled by the program.The whole system of simple structure turns out to be having a good effect after being tested. |
