Abstract

An 8-channel ultra low power programmable wireless ExG (ECG, EMG and EEG) system-on-chip (SoC) design for bio-signal processing applications is presented in this paper. The proposed design consists of a capacitive coupled programmable gain instrumentation amplifier (CC-PGIA) with an improved transconductance of amplifier. A 12-bit programmable hybrid SAR-Cyclic analog-to-digital converter (ADC) is introduced for improved performance and low power consumption that consists of a 6-bit SAR ADC (SADC) followed by a 6-bit cyclic ADC (CADC). The remaining blocks implemented in the SoC are programmable low pass filter (PLPF), programmable wireless transmitter (PWT), power management unit (PMU) and a digital block. The proposed programmable wireless ExG (PW-ExG) design is implemented in 180 nm standard CMOS process with a core area of 4 mm2. The performance parameters are found to be, power consumption of 286 µW @ 0.6 V supply voltage, input referred noise voltage of 0.96 µVrms over 0.5 Hz–1 kHz range, gain of 30–65 dB and signal-to-noise-and-distortion ratio (SNDR) of 69.2 dB.
