摘要:In this paper, design of sub-circuits of switched capacitor filter using 0.18μm CMOS technology. Thebasic building blocks of switched capacitor filters are sample-and-hold circuit, non-overlapping clock and a gain stage.The fully integrated designs of a low pass filter having cut-off frequency of 150Hz and a high pass filter having cut-offfrequency of 0.05Hz using switched capacitor circuits are presented. This combination of a low pass filter and a highpass filter results in a band pass filter which have the bandwidth of 0.05Hz to 150Hz, which is ideal in detecting ECGsignals. The filters are made with the help of op-amps whose gain is 47.119 dB.
