Question: 1
A.
[15 Marks]
For the circuit shown in Fig. 1, the transistors
parameters are: $V_{TN} = 1V$, $\mu_nC_{ox} = 44.4\mu A/V^2$, $\lambda = 0$, and
$L = 1\mu m$.
Assume Q1, Q2 and Q3 are identical.
i) Determine the value of V1.
ii) Design the transistors sizes (find W3) such that
$V_2 = 3V$.
iii) Determine the mode of operation of each
transistor.
