Course is VLSI

A CMOS inverter circuit uses NMOS and PMOS transistors with the following characteristics:

Vth mn/Cox W/L
NMOS 0.3V 100 (mA/V2) 2
PMOS 0.3V 50 (mA/V2) 2

Both transistors are saturated for a certain input (gate) voltage.

(a) Find an expression (value the input voltage as a function of supply voltage, VDD (hint: current through the NMOS and the PMOS are same).

(b) Plot ID vs VGS for VDS = 1.0V in the NMOS transistor above using excel.

(c) Plot ID vs VDS for VGS = 1.0V for the same NMOS using excel.
