Abstract :
This paper presents a low power, high linearity and high CMRR instrumentation amplifier (IA) based on a multiple-input floating gate fully differential second-generation current conveyor (FGFDCCH) for ECG acquisition systems. The proposed IA is included with the low power lossless integrator for the differential electrode offset (DEO) rejection. The proposed IA is designed and simulated with the AMS 0.35μm CMOS process. The simulation results exhibit CMRR of 117dB@50Hz, 0.16%THD@10Hz and 5mVpp input, and a DEO rejection capability up to ±200mV while consumes a supply current of 13μA with a 3V(±1.5V) supply voltage.
