Transconductance using Collector Current Solution

STEP 0: Pre-Calculation Summary

Formula Used

Transconductance = Collector Current/Threshold Voltage
G_m = I_c/V_th
This formula uses 3 Variables

Variables Used

Transconductance - (Measured in Siemens) - Transconductance is the ratio of the change in current at the output terminal to the change in the voltage at the input terminal of an active device.
Collector Current - (Measured in Ampere) - Collector current is an amplified output current of a bipolar junction transistor.
Threshold Voltage - (Measured in Volt) - Threshold voltage of transistor is the minimum gate to source voltage that is needed to create a conducting path between the source and drain terminals.

STEP 1: Convert Input(s) to Base Unit

Collector Current: 5 Milliampere --> 0.005 Ampere (Check conversion here)
Threshold Voltage: 5.5 Volt --> 5.5 Volt No Conversion Required

STEP 2: Evaluate Formula
