0. 4V, Low Power GmC Integrator And Bandpass Filter Design For EMG Bio Medical Signal Processing

This paper presents a novel 0.4 V G
_m
C integrator design approach and fourth order bandpass filter design for EMG biomedical applications with high DC gain and and low power consumption. The filter and integrator are implemented with a new architecture in 180nm CMOS process. By using negative resistance in proposed integrator the response can be controllable. The negative resistance in this paper is implemented with Operational Trans Conductance Amplifier(OTA) The response of proposed integrator is close to ideal integrator behavior.The OTA used in this work is operated with 0.4 V supply and bulk driven structure. The maximum power consumption of integrator is 45 nW and cut off frequency is 160 Hz. The fourth order bandpass filter is consumes 117nW power with bandwidth 260 Hz. The dynamic range of the filter is 63dB.
