Hi! Here is my task: Calculate RC1, RC2, RE2 for maximum undistorted symmetrical signal at output if DC collector currents are IC1=IC2=1mA. Calculate voltage gain Av. Vcc=9V, RE1=1.8kΩ , VBE=0.7V, VCES=0.2V, VT=26mV, beta=100, VA→∞. Solution: RE2=700Ω, RC1=5.724kΩ, RC2=3.141kΩ, Av=gm1*gm2*rpi2*RC1*RC2/(rpi2+RC1). After assuming that BJT's operate in forward active mode and solving circuit bellow I got RE2=700Ω, RC1=5.782kΩ. Is it ok? How to find RC2? I have no problems calculating Av.
