Gate Leakage through Gate Dielectric Solution

Follow our step by step solution on how to calculate Gate Leakage through Gate Dielectric?

FIRST Step Consider the formula

i g = (\frac{P st}{V bc}) - (i st + i con + i j)

Next Step Substitute values of Variables

∴

i g = (\frac{67.37mW}{2.02V}) - (1.6mA + 25.75mA + 1.5mA)

Next Step Convert Units

∴

i g = (\frac{0.0674W}{2.02V}) - (0.0016A + 0.0258A + 0.0015A)

Next Step Prepare to Evaluate

∴

i g = (\frac{0.0674}{2.02}) - (0.0016 + 0.0258 + 0.0015)

Next Step Evaluate

∴

i g = 0.00450148514851485A

Next Step Convert to Output's Unit

∴
