5.13 An n-channel device has k n = 100 μA/V2, Vt = 0.7 V, and W/L = 20. The device is to operate as a switch for small v DS, utilizing a control voltage vGS in the range 0 V to 5 V. Find the switch closure resistance, rDS, and closure voltage, VDS, obtained when vGS = 5 V and iD = 1 mA. If μp  0.4μn, what must W/L be for a p-channel device that provides the same performance as the n-channel device in this application?
