In Fig. P6.51 let R 5 3 kV and let the diode have VD(on) 5 0.7 V. Suppose vS in Fig. P6.51a, after having been at 14 V for a suffi ciently long time, is switched to 24 V, and the storage time is measured to be 25 ns. If D and R are swapped as shown in Fig. P6.51b and vS, after having been at 15 V for a long time, is switched to 25 V at t 5 0, sketch and label vS and vO vs. time for t $ 0 and comment (for simplicity assume Cj 5 constant 5 5 pF).
