Turning the Circuit into Small Signal Model In order to obtain the small signal circuit, we need to turn all large signal (DC) elements into its corresponding small signal elements. For example, The transistor would be replaced by the small signal model circuit Constant voltage and constant current would be eliminated from the circuit ,\$\begingroup\$ You need to understand what gain means in such transistor/mosfet based amplifiers. Such circuits dont have, what is called large signal gain. They have small signal gains related to small signal parameters. You have calculated the value of Vs when Vi = 0. That is correct but doesnt tell you to gain, rather the operating point. the weather channel official website Diffusion small since few carriers have enough energy to penetrate barrier Drift current is small since minority carriers are few and far between: Only minority carriers generated within a diffusion length can contribute current Important Point: Minority drift current independent of barrier!
