Design the inverter circuit in the below figure to provide VDD = 1.2 V, VOL = 50 mV, and so that the current the supply in the low-output state is 30 μA. The transistor has Vt = 0.4 V, μnCox = 500 μA/V2, and λ = 0. (a) Determine the required values of rDS, RD, and W/L. (b) How much power is drawn from the supply when the output is low? (c) How much power is drawn from the supply when the output is high?

D14.1 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 = 1.8 V. 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, rDS ≃ 1 /[(μnCox)(W/L)(VGS − Vt)] Ans. 1.9; 57 kΩ; 0; 54 μW (a)D14.1 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.
