Lecture

Introduction to Small Signal Configurations

Description

This lecture introduces the concept of small signal configurations in electronics, focusing on the modeling of transistors and their polarizations. It covers the use of models in quadrupoles, input and output resistors, voltage gain, current gain, and trans-resistance/trans-conductance. The instructor explains the methodology for studying configurations, determining key parameters like rin, rout, and gmo, and simplifying calculations using approximations. Emphasis is placed on choosing the appropriate assembly for electronic applications.
