2.(20%) Figure 2 shows the differential amplifier. Please find (a) the differential gain, (b) the differential input resistance, (c) the common-mode gain assuming the resistance Rc have 2% tolerance, and (d) the common-mode input resistance. For these transistors, β = 100, thermal voltage is 25.9 mV and Early voltage VA = 100 V. (5%*4)
