Output Current of Wilson Current Mirror Solution

Follow our step by step solution on how to calculate Output Current of Wilson Current Mirror?

FIRST Step Consider the formula

I o = I ref \cdot (\frac{1}{1 + (\frac{2}{β^{2}})})

Next Step Substitute values of Variables

∴

I o = 7.6mA \cdot (\frac{1}{1 + (\frac{2}{2^{2}})})

Next Step Convert Units

∴

I o = 0.0076A \cdot (\frac{1}{1 + (\frac{2}{2^{2}})})

Next Step Prepare to Evaluate

∴

I o = 0.0076 \cdot (\frac{1}{1 + (\frac{2}{2^{2}})})

Next Step Evaluate

∴

I o = 0.00506666666666667A

Next Step Convert to Output's Unit

∴

I o = 5.06666666666667mA

LAST Step Rounding Answer

∴

I o = 5.0667mA
