Voltage Gain given Transconductance and Collector Resistance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Voltage Gain = -Transconductance*Collector Resistance
A_v = -G_m*R_c
This formula uses 3 Variables

Variables Used

Voltage Gain - (Measured in Decibel) - Voltage gain is defined as the ratio of the output voltage to the input voltage.
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 Resistance - (Measured in Ohm) - Collector Resistance (Rc)helps to set the transistor at the "operating point" of the amplifier. The purpose of the emitter resistor Re is to prevent "thermal runaway".

STEP 1: Convert Input(s) to Base Unit

Transconductance: 1.72 Millisiemens --> 0.00172 Siemens (Check conversion here)
Collector Resistance: 3.75 Kilohm --> 3750 Ohm (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_v = -G_m*R_c --> -0.00172*3750

Evaluating ... ...
