Question
The switches as shown can be implemented
using MOSFETs, as shown. What
are the W/L ratios of the transistors if the onresistance
of the transistor is to be less than 1 percent
of the resistor 2R = 10 kohm ? Assume that
the voltage applied to the gate of the MOSFET is
5 V when b1 = 1 and 0 V when b1 = 0. For the
MOSFET, VTN = 1 V, K'n= 50 A/V2, 2φF = 0.6
V, and γ = 0.5√V.
