Description

This lecture covers the Chopper Stabilization (CHS) technique in low-power Analog IC Design. It explains how CHS applies modulation to shift noise to higher frequencies, reducing offset and low-frequency noise. The lecture details the CHS principle, equivalent DC gain, effects on amplifier white and 1/f noise, total amplifier noise, residual offset, and experimental chopper amplifiers. It also discusses the effect of chopping on amplifier noise, residual offset, and input offset voltage. The lecture concludes with a summary of the CHS technique and its benefits.
