Amplifier Noise Analysis

This lecture covers the analysis of noise in amplifier circuits, focusing on small signal operation and noise sources. The instructor explains the noise analysis of a Miller amplifier and a single-stage operational transconductance amplifier, emphasizing the importance of perfect matching between transistors. The lecture delves into calculating output noise current, noise conductance, and the impact of noise sampling in circuits. The instructor illustrates how noise is replicated across frequencies due to sampling, leading to aliasing and increased noise at low frequencies. The lecture concludes with insights on power conservation in noise analysis and the trade-offs in analog circuit design.
