NMOS IV Characteristics

* To plot results in AvanWaves
* Open nmos_iv.sp
* Select DC: NMOS IV Characteristics
* Apply the drain voltage to the X-Axis
*    single click Types:Voltages
*    single click Curves:drain
*    single click Current X-Axis:Apply
* Apply the m1 drain current to the Y-Axis
*    single click Types:Current 1
*    double click i1(m1)

* There's only a single MOSFET in the netlist
m1 drain gate Gnd Gnd CMOSN l=0.5u w=2u

* Voltage sources on the gate and drain initially set to 0
Vgate gate Gnd 0
Vdrain drain Gnd 0

* perform a nested voltage sweep
* inner sweep: Vdrain from 0 to 5 by .1
* outer sweep: Vgate from 0 to 5 by 1

.DC Vdrain 0 5 .1 Vgate 0 5 1

* printing MOS currents: I1-drain, I2-gate, I3-source
.print dc I1(m1)
