Inverter characteristics
Goals
Experiments
Determine Iout versus Vin of the transconductor using the circuit above. Vary the input voltage from 0 to Vcc. You can use a separate power supply for generating the variable bias voltages or a resistive voltage divider(say, a chain of 16 identical resistors from Vcc to ground). What is the self bias voltage VM of the inverter? Estimate the transconductance at VM. Choose the supply voltagesfor the opamp appropriately so that it doesn't saturate .
Exercises
You'll need the measured parameter values for subsequent experiments(gm,inv, rout,inv, VTp, VTn, μpCox, μnCox). So keep a record of them.
