This formula uses 4 Variables
Variables Used
Transconductance - (Measured in Siemens) - Transconductance is defined as the ratio of the change in the output current to the change in the input voltage, with the gate-source voltage held constant.
Transconductance Parameter - (Measured in Ampere per Square Volt) - Transconductance parameter is a crucial parameter in electronic devices and circuits, which helps to describe and quantify the input-output relationship between voltage and current.
Gate-Source Voltage - (Measured in Volt) - Gate-source voltage is a critical parameter that affects the operation of an FET, and it is often used to control the device's behavior.
Threshold Voltage - (Measured in Volt) - Threshold voltage, also known as the gate threshold voltage or simply Vth, is a critical parameter in the operation of field-effect transistors, which are fundamental components in modern electronics.
STEP 1: Convert Input(s) to Base Unit
Transconductance Parameter: 10.5 Ampere per Square Volt --> 10.5 Ampere per Square Volt No Conversion Required
Gate-Source Voltage: 4 Volt --> 4 Volt No Conversion Required
