In Fig. P6.52 let R 5 2 kV and v2 5 2.5 V, and let the diode have VD(on) 5 0.7 V and F 5 20 ns. (a) If v1, after having been at 0 V for a long time, is switched to 15 V at t 5 0, sketch and label v1 and vO vs. time for t $ 0 and comment (for simplicity assume Cj 5 constant 5 5 pF). (b) Repeat part (a), but for the case in which v1 is switched to 12.5 V (instead of 15 V).
