Bias Current in Differential Pair Solution

Follow our step by step solution on how to calculate Bias Current in Differential Pair?

FIRST Step Consider the formula

I b = I d1 + I d2

Next Step Substitute values of Variables

∴

I b = 7.65mA + 7.51mA

Next Step Convert Units

∴

I b = 0.0076A + 0.0075A

Next Step Prepare to Evaluate

∴

I b = 0.0076 + 0.0075

Next Step Evaluate

∴

I b = 0.01516A

LAST Step Convert to Output's Unit

∴

I b = 15.16mA
