Output resistance of the Wilson MOS Mirror Solution

STEP 0: Pre-Calculation Summary
Formula Used
resistance_output = (MOSFET Transconductance*Finite output resistance)*Final Resistance
Ro = (gm*Ro )*Ω
This formula uses 3 Variables
Variables Used
MOSFET Transconductance - MOSFET Transconductance is the change in the drain current divided by the small change in the gate/source voltage with a constant drain/source voltage. (Measured in Microsiemens)
Finite output resistance - The finite output resistance is the measure of the opposition to current flow, both static and dynamic, into the load network being connected that is internal to the electrical source. (Measured in Ohm)
Final Resistance - Final Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). (Measured in Ohm)
STEP 1: Convert Input(s) to Base Unit
