Design the inverter in Fig. 14.12(a) to provide VOL = 90 mV and to draw a supply current of 30 A in the low-output state. Let the transistor be specified to have Vt = 0.4 V, nCox = 125 A/V2

Design the inverter in Fig. 14.12(a) to provide VOL = 90 mV and to draw a supply current of 30 μA in the low-output state. Let the transistor be specified to have Vt = 0.4 V, μnCox = 125 μA/V2 , and λ = 0. The power supply VDD = 1.8V. Specify the required values of W/L and RD. How much power is drawn from VDD when the switch is open? Closed? Hint: Recall that for small vDS ,
