I don't know who's R2...VCC= 10V;VCM = 1.5V;vg is a sine wave with a frequency of 1 kH, R1 it's 15k..I need to: a)Calculate the theoretical expressions of the DC collector currents of bipolar transistors Q1–Q8, considering VBE≈ 0.6V. Calculate the theoretical expression of the small-signal voltage gain Av= vo/vg. b)choose a value for R2 and C∞) in order to have a(theoretical)gain value Av= 1500.
