WebThe slope is Δ I / Δ V, which is 1 / R and R is the effective resistance of the MOSFET at the chosen voltage/current point. The resistance will obviously be different at different points on the curves. Of course, this only makes sense for the regions of operation where the current changes as a function of voltage (the linear or triode region). WebQuestion: 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 1.
