The parameters for each transistor in the circuit shown in Figure P6.75 are β = 100 and VA = ∞. (a) Determine the small-signal parameters gm , rπ , and ro for both transistors. (b) Determine the small-signal voltage gain Av1 = vo1/vs, assuming vo1 is connected to an open circuit, and determine the gain Av2 = vo/vo1. (c) Determine the overall small-signal voltage gain Av = vo/vs. Compare the overall gain with the product Av1 · Av2, using the values calculated in part (b)
