Consider the two-transistor diode-connected circuit in Figure P10.49. Assume that both transistors are biased in the saturation region, and that \(g_{m 1}=g_{m 2} \equiv g_{m}\) and \(r_{o 1}=r_{o 2} \equiv r_{o}\). Neglect the body effect. Derive the expression for the output resistance \(R_{o}\).
