Source-Degenerated Time Constant of CS Amplifier Solution

Follow our step by step solution on how to calculate Source-Degenerated Time Constant of CS Amplifier?

FIRST Step Consider the formula

T sd = C gs \cdot R s + C gd \cdot R gd + C t \cdot R t

Next Step Substitute values of Variables

∴

T sd = 2.6μF \cdot 25kΩ + 1.345μF \cdot 0.5kΩ + 2.889μF \cdot 0.48kΩ

Next Step Convert Units

∴

T sd = 2.6E-6F \cdot 25000Ω + 1.3E-6F \cdot 500Ω + 2.9E-6F \cdot 480Ω

Next Step Prepare to Evaluate

∴

T sd = 2.6E-6 \cdot 25000 + 1.3E-6 \cdot 500 + 2.9E-6 \cdot 480

Next Step Evaluate

∴

T sd = 0.06705922s

LAST Step Rounding Answer

∴

T sd = 0.0671s
