Noise in Devices and Circuits

This lecture covers the different types of noise in devices and circuits, including interference noise, inherent noise, and random signals. It explains the concepts of random processes, mean value, autocorrelation, stationary processes, power spectral density, and noise power. The lecture also delves into cross-correlation, noise summation, and the impact of linear systems on noise. Furthermore, it discusses thermal noise, shot noise, flicker noise, and their contributions to total noise power. Various noise models for circuit components such as resistors, diodes, MOSFETs, and op-amps are explored, along with their noise calculations and characteristics.
