Noise in Two-port Networks

This lecture covers the analysis of noise in two-port networks, including the equivalent circuit, capacitances scaling, Y-parameters, direct extraction of small-signal circuit components, and measured versus analytical Y-parameters. It also discusses the extraction of substrate resistance, gate resistance, and the simplified small-signal circuit. The lecture delves into the noise factor, correlation admittance, power spectral densities, and equivalent noise resistance. Furthermore, it explores the noise factor of noisy two-port networks, noise parameters, and the Friis formula for cascaded amplifiers.
