First Drain Current of MOSFET on Large-Signal Operation Solution

Follow our step by step solution on how to calculate First Drain Current of MOSFET on Large-Signal Operation?

FIRST Step Consider the formula

I d1 = \frac{I b}{2} + \frac{I b}{V ov} \cdot \frac{V id}{2} \cdot \sqrt{1 - \frac{{V id}^{2}}{4 \cdot {V ov}^{2}}}

Next Step Substitute values of Variables

∴

I d1 = \frac{985mA}{2} + \frac{985mA}{3.12V} \cdot \frac{0.03V}{2} \cdot \sqrt{1 - \frac{{0.03V}^{2}}{4 \cdot {3.12V}^{2}}}

Next Step Convert Units

∴

I d1 = \frac{0.985A}{2} + \frac{0.985A}{3.12V} \cdot \frac{0.03V}{2} \cdot \sqrt{1 - \frac{{0.03V}^{2}}{4 \cdot {3.12V}^{2}}}

Next Step Prepare to Evaluate

∴

I d1 = \frac{0.985}{2} + \frac{0.985}{3.12} \cdot \frac{0.03}{2} \cdot \sqrt{1 - \frac{{0.03}^{2}}{4 \cdot {3.12}^{2}}}

Next Step Evaluate

∴

I d1 = 0.497235522193922A

Next Step Convert to Output's Unit

∴

I d1 = 497.235522193922mA

LAST Step Rounding Answer

∴

I d1 = 497.2355mA
