Questions & Step-by-Step Solutions
In small-signal models, which parameter represents the transconductance of a FET?
Step 1: Understand what a FET is. A FET (Field Effect Transistor) is a type of transistor used to control electrical signals.
Step 2: Learn about small-signal models. These models help analyze how a FET behaves with small changes in input signals.
Step 3: Identify the key parameters in small-signal models. One important parameter is transconductance.
Step 4: Know what transconductance means. It measures how much the drain current (output current) changes when the gate-source voltage (input voltage) changes.
Step 5: Recognize the symbol for transconductance. In small-signal models, transconductance is represented by the letter 'gm'.
