An N-Channel device has K’n = 50 µA / V^2, Vt = 0.8 V and W/L =20. The device is operating as a switch for small Vds, utilizing acontrol voltage Vgs in the range 0 V to 5 V. Find the switchclosures resistance, Rds and closure voltage, Vds obtained when Vgs= 5 V and Id = 1 ma. Recalling that Up (Miu)= 0.4 µ(n). What mustW/L be for a p-channel device that provides the same performance asthe n-channel device in this application?
