Let \(\beta=25\) for the transistor in the circuit shown in Figure P17.37.

(a) For no load, determine the parameters \(i_{1}, i_{B}, i_{C}, v_{1}\), and \(v_{O}\) when (i) \(v_{I}=0\) and (ii) \(v_{I}=1.5 \mathrm{~V}\).

(b) Determine \(v_{I}, v_{1}, i_{B}\), and \(i_{C}\) for the case (i) where the output transistor just begins to conduct and (ii) where the output transistor just goes into saturation.

(c) Assume that \(N\) similar type load circuits are connected to the output. Determine the maximum number \(N\) such that the output transistor remains in saturation.
