Total Instantaneous Gate-to-Source Voltage Formula Elements

Variables
Gate to Source Voltage
Gate to source voltage of transistor is the voltage that falls across the gate-source terminal of the transistor.
Symbol: Vgs
Measurement: Electric PotentialUnit: V
Note: Value should be greater than 0.
Small Signal
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).
Symbol: Vss
Measurement: Electric PotentialUnit: V
Note: Value can be positive or negative.
Voltage Across Oxide
Voltage across oxide due to the charge at the oxide-semiconductor interface and the third term is due to the charge density in the oxide.
Symbol: Vox
Measurement: Electric PotentialUnit: V
Note: Value can be positive or negative.
