For an NMOS differential pair, let VDD = VSS = 2.5 V, kn’W/L = 3 mA/V2, Vtn = 0.7 V, I = 0.2 mA, RD = 5 kΩ, and neglect channel-length modulation. With G2 grounded and vG1 = vid. Let vid be adjusted to the value that causes iD1 = 0.11 mA and iD2 = 0.09 mA. Find the corresponding values of vGS2, vs, vGS1, and hence vid. What is the difference output voltage vout = vD2 - vD1 ? What is the voltage gain (vD2 - vD1)/vid ? What value of vid results in iD1 = 0.09 mA and iD2 = 0.11 mA ?

For an NMOS differential pair, It VDD = VSS =2.5 V, kn'W/L = 3 mA/V2, Vtn = 0.7 V, I = 0.2 mA, RD = 5kohm, and neglect channel-length modulation. Let vG2 = 0 and vG1 = vid. Find the value of vid that corresponds to each of the following situations: a) iD1 = iD2 = 0.1 mA b) iD1 = 0.15 mA and iD2 = 0.05 mA c) iD1 = 0.2 mA and iD2 = 0 mA d) iD1 = 0.05 mA and iD2 = 0.15 mA e) iD1 = 0 mA and iD2 = 0.2 mA For each case, find vS, vD1, vD2, and (vD2 - vD1).
