Problem 1: Consider the MOS amplifier in Fig. 1
\mu _(n)C_(ox )=400\mu (A)/(V^(2))
\mu _(p)C_(ox )=200\mu (A)/(V^(2))
V_(THN )=|V_(THP )|=0.3V
V_(DD)=1.2V
Channel length modulation is ignored for both M_(1) and M_(2).
The C_(BY) and R_(B)?10\mu F and 100k\Omega V_(in )=40mW\times cos(2\pi \times 10^(4)t),
(a) Simulate the circuit of Fig. 1, and show the output and input voltage
waveforms
(b) Compare the simulated gain with the calculation
