Q1. All transistors shown in Figure 1 are identical. They have the following properties: ẞ = 200, VT = 0.026 V and VBE = 0.7 V. In order to set the bias current of the differential amplifier to I = 1.8 mA (see Figure 1), determine the value of the resistor, R. Determine the DC output voltage at the output terminals V01 and V02. The input signal to the differential amplifier is given as (v1 - Viz) = 12 sin(wt) mV, determine the total output voltage at terminal vo1. Explain how to eliminate the DC voltage at the output terminal, V01. Sketch a circuit diagram that can fulfil this requirement. R +20 V 20 ΚΩ Vil V02 ના 50711 20 ΚΩ I = 1.8 mA Viz
