This formula uses 4 Variables
Variables Used
Drain Voltage Q2 - (Measured in Volt) - Drain Voltage Q2 is voltage taken at Drain terminal at one transistor Q2 in Differential Circuit.
Output Resistance - (Measured in Ohm) - Output resistance refers to the resistance of an electronic circuit to the flow of current when a load is connected to its output.
Transconductance - (Measured in Siemens) - Transconductance is defined as the ratio of the change in the output current to the change in the input voltage, with the gate-source voltage held constant.
Common Mode Input Signal - (Measured in Volt) - A common mode input signal is a type of electrical signal that appears equally on both input terminals of a differential amplifier.
STEP 1: Convert Input(s) to Base Unit
Output Resistance: 4.5 Kilohm --> 4500 Ohm (Check conversion ​here)
Transconductance: 0.5 Millisiemens --> 0.0005 Siemens (Check conversion ​here)
Common Mode Input Signal: 84.7 Volt --> 84.7 Volt No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
vo2 = -(Rout/((1/gm)+2*Rout))*Vcin --> -(4500/((1/0.0005)+2*4500))*84.7
Evaluating ... ...
vo2 = -34.65
STEP 3: Convert Result to Output's Unit
-34.65 Volt --> No Conversion Required
-34.65 Volt <-- Drain Voltage Q2
