Abstract

A programmable OTA-C band-pass filter operating in sub-threshold region for use in bionic ears is presented. Design details together with simulation results are given. The filter has been fabricated using BSIM3v3.2 models from the AMS process for 0.35μm CMOS C35 Technology, and tested experimentally. It operates with ±1.5V supply rails features power consumption of 11.25nW and 546nW for frequency bands (100-200) Hz and (5-10) kHz respectively. The design features an input linear range of ±900mV, with total harmonic distortion <;5% and offers a dynamic range of 65.36dB.
