1 n Given a differential amplifier in equilibrium as shown in Fig. 5, (a) i. find the differential gain, ii. find the common mode gain, iii. find the CMRR. (Voltage to keep the transistors in saturation is 0.8V (DC voltage at gate) and small-signal voltage is Vin = 4sin(100KHz) mV.) The solution should consist of output waveform for part i. and part ii. - (b) Properly explain the following concepts involved while solving for differential gain and common mode gain. i. What is the small signal input given in case of differential gain and in case of common mode gain? ii. What is the significance of CMRR? Compare the CMRR obtained in iii with the ideal CMRR. iii. What non-idealities lead to finite CMRR? Vg1 sine 100 kHz ww R1 100 M3 + M4 + V3 -1.62 V Fig. 5 R2 100 V2 1.62 V Vg2 sine 100 kHz 4 H ) U t. 3 3 'T . 3 II L L
