7 (8 marks) In the circuit of Fig. 7, assume that ISS = 1 mA and (W/L) = 50/0.5 for all the transistors. The circuit is fully symmetric. VDD = 3 V, kn′ = 4kp′ = 400 μA/V2, |VTn,p| = 0.6 V a. Determine the voltage gain with ID5 = ID6 = 0.9(ISS/2). b. Calculate Vb such that ID5 = ID6 = 0.9(ISS/2). c. If ISS requires a minimum voltage of 0. 3 V, what is the maximum differential output swing?

(8 marks) In the circuit of Fig.7, assume that $I_{S S} = 1 m A$ and $(W / L) = 50 / 0.5$ for all the transistors. The circuit is fully symmetric. $V_{D D} = 3 V, k_{n}^{'} = 4 k_{p}^{'} = 400 μ A / V^{2}, | V_{T n, p} | = 0.6 V$ a. Determine the voltage gain with $I_{D 5} = I_{D 6} = 0.9 (I_{S S} / 2)$ . b. Calculate $V_{b}$ such that $I_{D 5} = I_{D 6} =$ $0.9 (I_{S S} / 2)$ . c. If $I_{S S}$ requires a minimum voltage of $0.3 V$ , what is the maximum differential output swing? Fig. 7 (4) $I_{s s}$
