## Overall voltage gain of the amplifier Solution

STEP 0: Pre-Calculation Summary
Formula Used
Gv = (1/RD+1/Rl)/(Rs+1/kn)
This formula uses 4 Variables
Variables Used
Load resistance of MOSFET - Load resistance of MOSFET is the effective resistance of all of the circuit elements excluding the emf source (Measured in Ohm)
Load resistance - Load resistance is the resistance value of load given for the network (Measured in Kilohm)
Signal Resistance- Signal Resistance is the resistance which is fed with the signal voltage source vs to an Amplifier
MOSFET transconductance parameter - MOSFET transconductance parameter is the product of the process transconductance parameter kn and the transistor aspect ratio (W/L). (Measured in Mho)
STEP 1: Convert Input(s) to Base Unit
Load resistance of MOSFET: 200 Ohm --> 200 Ohm No Conversion Required
