Reference Current of Wilson Current Mirror Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
Output Current - (Measured in Ampere) - Output Current is the current the amplifier draws from the signal source.

STEP 1: Convert Input(s) to Base Unit

Transistor Current Gain: 2 --> No Conversion Required
Output Current: 5 Milliampere --> 0.005 Ampere (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula
