Prelab: 1. For the amplifier circuits in Figs. 1, 2, 3, and 4: a. Calculate the Q-point values of collector current (Ic) and collector-emitter voltage (VCE). Assume BDC-150, VBE=0.65 V, VCE(SAT) -0.2 V, and VA = ∞. Put your results in the prelab columns of Table 1. b. Calculate the small-signal voltage gain Vout/Vin. Assume BAC-150 and the capacitors are short circuits. Put your results in the prelab columns of Table 2. Record the gain magnitude in column 2 and the phase shift in column 3. A non-inverting gain has a phase shift of 0° and an inverting gain has a phase shift 180°.
