Q.2(a) A PMOS transistor is fabricated with the following specifications:
$V_{TO,p} = -0.5V$, $\gamma = -0.25 V^{0.5}$, $\lambda = -0.05 V^{-1}$, $\varphi_{Fp} = 0.2 V$, $k' = 20 \mu A/V^2$.
(i) Given $I_D = 8.48 \mu A$, $V_S = 1.2V$, $V_B = 1.8V$, $V_G = 0.2V$, $V_D = 0V$. What is the transistor region of operation? Calculate W/L.
(ii) Given $V_S = 1.2V$, $V_B = 1.8V$, $V_G = 0V$, $V_D = 1V$. What is the transistor region in this case? Calculate $I_D$.
