Equivalent Resistance of Cascode Amplifier Solution

Follow our step by step solution on how to calculate Equivalent Resistance of Cascode Amplifier?

FIRST Step Consider the formula

R dg = {(\frac{1}{R out1} + \frac{1}{R in})}^{- 1}

Next Step Substitute values of Variables

∴

R dg = {(\frac{1}{1.201kΩ} + \frac{1}{0.301kΩ})}^{- 1}

Next Step Convert Units

∴

R dg = {(\frac{1}{1201Ω} + \frac{1}{301Ω})}^{- 1}

Next Step Prepare to Evaluate

∴

R dg = {(\frac{1}{1201} + \frac{1}{301})}^{- 1}

Next Step Evaluate

∴

R dg = 240.679760319574Ω

Next Step Convert to Output's Unit

∴

R dg = 0.240679760319574kΩ

LAST Step Rounding Answer

∴

R dg = 0.2407kΩ
