The transistor parameters for the circuit in Figure P16.21 are: VTN = 0.8 V for all enhancement-mode devices, VTN = −2 V for the depletion-mode devices, and kn' = 60 μA/V2 for all devices. The width-to-length ratios of ML2 and ML3 are 1, and those for MD2, MD3, and MD4 are 8. (a) For vX = 5 V, output vO1 is 0.15 V, and the power dissipation in this inverter is to be no more than 250 μW. Determine (W/L)M L1 and (W/L)M D1.
