Noise Reduction Techniques in Analog Circuits

This lecture covers noise and offset reduction techniques in analog circuits, focusing on Autozero (AZ) and Chopper Stabilization (CS). It explains how these techniques work, their impact on noise and offset, and the trade-offs involved. The Autozero technique involves sampling to cancel offset and reduce flicker noise, while the Chopper Stabilization technique shifts 1/f noise to higher frequencies without increasing white noise. The lecture discusses the principles, implementations, and experimental results of these techniques.
