Determine the input impedance and load voltage for the small signal model of amplifier in Fig. 7. Here gm = 1 mA/V, Vsig = 25 mV, VDD = 22 V, RG = 1.2 Mohm, RD = 1.6 kohm, Rs = 20 ohm, RL =12 kohm and ignore ro. Label small signal model properly.
Analyze the operation mode of the MOS differential pair of Fig. 15. Consider VDD = VSS = 1.5 V, kn'(W/L) = 4mA/V^2, Vt = 0.6V, I = 0.4mA and RD = 2.4kohm to calculate: i) VOV and VGS for each transistor & ii) VS, iD1, iD2, VD1, VD2 for VCM = 1 V
