A BJT amplifier with active load is shown in Figure P10.83. The circuit contains emitter resistors (R_{E})

Question:

A BJT amplifier with active load is shown in Figure P10.83. The circuit contains emitter resistors $R_{E}$ and a load resistor $R_{L}$.

(a) Derive the expression for the output resistance looking into the collector of $Q_{2}$.

(b) Using the small-signal equivalent circuit, derive the equation for the small-signal voltage gain. Express the relationship in a form similar to Equation (10.94).
