Design and Implementation of Tunable Bandpass Filter for Biomedical Applications

A realization of on-chip large resistance using aswitched-capacitor series to parallel topology is presented in thispaper. Using this scheme, a band-pass filter for various biomedicalapplications such as EEG, ECG, EOG at a very low cornerfrequency upto 0.01 Hz in 180 nm CMOS, N-well technology with1.8 V supply voltage and was simulated using Cadence Spectresimulator. Simulation results show that the band pass filter wasdesigned with different bandwidth ranges for various biomedicaldevice application.
