Abstract :
We said in the previous article that looking into a node, one can see the Thevenin or Norton equivalent circuit for that node. We now look deeper into one particular circuit that consists of an NMOS transistor with a resistor in series with its source terminal in a configuration known as NMOS transistor with source degeneration. We offer a simple method for the small-signal analysis and design of this configuration. The case for the PMOS transisor is similar but not discussed in this article for brevity.
