This paper reports the fabrication of a readout integrated circuit for various environmental gas sensors in a TSMC 0.25 pm CMOS process. It has an area of 6.67 mm 2 and a power consumption of 17.5 mW at a supply voltage of 2.5 V. The proposed readout integrated circuit has four input channels and ca...
