Example 3.1

1. Schematic

2. HSPICE Netlist

* Example 3.1

* MOS model
.include p35_cmos_models_tt.inc

* main circuit
mn1 2 2 0 0 nmos L=0.4u W=10u
mn2 1 2 0 0 nmos L=0.4u W=10u

* current source
id 0 2 100u

* voltage source
v1 1 0 0.795

** v1 dc value adjusted to ensure Id is 0.1mA

* analysis
.op
.dc v1 0 1 10m

* options
.options post

.end

3. Simulation Result

r_{out [kΩ]}	g_m1 [mA/V]	ΔI_out [µA]	the minimum V_ds [mV]
43	0.99	2.5	280

Hello,
I simulated this example in LTSpice using the provided models, but I get quite different results than those shown here.
Do you have any insight into this?

Thanks!

Would love your thoughts, please comment.x
