Let β = 25 for the transistor in the circuit shown in Figure P17.37.
(a) For no load, determine the parameters i1, iB, iC , v1, and vO when (i) vI = 0 and (ii) vI = 1.5 V.
(b) Determine vI , v1, iB, and iC 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.
