The figure shows a differential amplifier with a differential input vid = (vin_d_pos - vin_d_neg) between the bases of Q1 and Q2, and an output (out) at the emitter of Q4. I have to Determine R1, R2, R4, R5 and R6 so that the following requirements are met: R 1 = R 2 Av = vout / vid = 100 [V / V] Vout = 0V when Vin_d_pos = Vin_d_neg = 0V. The output Vout must be able to deliver undistorted peak signal voltage in the range from vout-min to vout-max with RL armed. Quiescent current IC = 10 * Q3-Q4 IB ---------- I have been given the values: Vcc-pos = 21 V Vcc-neg = 21 V R3 = 2000 Ohm RL = 49 Ohm I1 = 3,56 mA Vout-max = 8,8 V Vout-min = -8,8 V ---------- How can I start? For I have difficulty getting started.
