Output Current of Wilson Current Mirror Solution

STEP 0: Pre-Calculation Summary

Formula Used

Output Current = Reference Current*(1/(1+(2/Transistor Current Gain^2)))
I_o = I_ref*(1/(1+(2/β^2)))
This formula uses 3 Variables

Variables Used

Output Current - (Measured in Ampere) - Output Current is the current the amplifier draws from the signal source.
Reference Current - (Measured in Ampere) - A reference current is just a stable source of current that does not fluctuate over temperature, supply voltages or loads.
Transistor Current Gain - Transistor current gain is highly influenced by two factors: the width of the base region, W, and the relative dopings of the base region and the emitter region.

STEP 1: Convert Input(s) to Base Unit

Reference Current: 7.6 Milliampere --> 0.0076 Ampere (Check conversion here)
Transistor Current Gain: 2 --> No Conversion Required
