- In this paper, a low-noise, low-power and low voltage Chopper Stabilized CMOS Amplifier (CHS-A) is presented and simulated using transistor model parameters of the AMS 0.35 μm CMOS process. This CHS-A is dedicated to high resistive gas sensor detection. The proposed CHS-A using Chopper Stabilization technique (CHS) exhibits an equivalent input referred noise of only 0.194 nV/√Hz for a chopping frequency of 210 kHz under ۫.25 V supply voltage and 26.5 dB voltage gain. The inband PSRR is above 90 and the CMRK exceeds 120 dB. At the same simulation condition, the total power consumption is 5 μW only.
