Small Signal in MOSFET Amplifiers Formulas

A small signal is an AC signal (more technically, a signal having zero average value) superimposed on a bias signal (or superimposed on a DC constant signal). And is denoted by V_ss. Small Signal is usually measured using the Volt for Electric Potential. Note that the value of Small Signal is always positive.

FAQ

What is the Small Signal?

A small signal is an AC signal (more technically, a signal having zero average value) superimposed on a bias signal (or superimposed on a DC constant signal). Small Signal is usually measured using the Volt for Electric Potential. Note that the value of Small Signal is always positive.

Can the Small Signal be negative?

No, the Small Signal, measured in Electric Potential cannot be negative.

What unit is used to measure Small Signal?

Small Signal is usually measured using the Volt[V] for Electric Potential. Millivolt[V], Microvolt[V], Nanovolt[V] are the few other units in which Small Signal can be measured.
