3.10 A 0.69/0.58-PEF 1.6nW/24nW Capacitively Coupled Chopper Instrumentation Amplifier with an Input-Boosted First Stage in 22nm/180nm CMOS

IEEE International Solid-State Circuits Conference
The front-end amplifier typically determines the noise level of a sensor system. Therefore, a highly power-efficient amplifier plays a critical role in Internet-of-Things (IoT) applications with stringent power constraints and small input amplitude [1, 2]

Reducing Switching Artifacts in Chopper Amplifiers

2018
This thesis describes the theory, design, and implementation of chopper operational amplifiers (op-amps) in CMOS integrated circuits (ICs). The chopping technique periodically corrects DC errors of such op-amps, so that low 1/f noise and stable, microvolt-level offset can be achieved.
