= = 0.8 V, B = 300, VT = 25 mV, VA = 20 V, VBE1 VBE2 = 1) For the circuit below, Vcc 00, R₁ = 230 kN, R₂ = 120 ΚΩ, Rc1 = 12 kn, Rc2 = 4 kN, RE₁ = 500 , RE2 2 kN, RE3 = 4.5 kn, and R₁ = 8 kN are given. Cos are very large coupling/bypass capacitors. a. Find the operating collector currents of Q₁ and Q₂. You should include the base current of Q₁ in your calculations, but you can neglect the base current of Q2. What is the voltage gain of the amplifier in dB? b. C. What is the input signal amplitude of a sinusoidal waveform that can be amplified without clipping at the output? Assume VCEsat = 1 V.
