5.23 When the drain and gate of a MOSFET are connected together, a two-terminal device known as a “diode-connected transistor” results. Figure P5.23(a) and Figure P5.23(b) show such devices obtained from MOS transistors of both polarities. Show that (a) the i–v relationship is given by (b) the incremental resistance r for a device operating at v = |V| + VOV is given by Figure P5.23 (a) Figure P5.23 (b)
