Term: MOSFET
Definition: A type of transistor used for amplifying or switching electronic signals.
Term: Transfer Characteristic
Definition: The relationship between input and output voltages in a circuit, illustrating how changes in input affect the output.
Term: Gain
Definition: A measure of the amplification ability of a circuit, defined as the ratio of output signal to input signal.
Term: Triode Region
Definition: The operational region of a MOSFET where it behaves as a variable resistor.
Term: Saturation Region
Definition: The operational region where the MOSFET is fully on and current is relatively constant regardless of the output voltage.
Term: Transconductance (gm)
Definition: A key parameter that indicates how effectively an input voltage controls the output current in a MOSFET.
