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. Chopping is used to modulate the offset away from the output signal where it can be easily filtered out, providing continuous offset reduction which is insensitive to drift. The CHS was simulated using typical...
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...
