Consider a four-input NMOS NOR logic gate with a depletion load similar to the circuit in Figure P16.19. Assume \(V_{D D}=2.5 \mathrm{~V}, V_{T N D}=0.4 \mathrm{~V}\), and \(V_{T N L}=-0.6 \mathrm{~V}\). The maximum value of \(v_{O}\) in its low state is to be \(50 \mathrm{mV}\).

(a) Determine \(K_{D} / K_{L}\).

(b) The maximum power dissipation in this NOR logic gate is to be \(50 \mu \mathrm{W}\). Determine the width-to-length ratio of each transistor.

(c) Determine \(v_{O}\) when (i) two inputs are a logic 1, (ii) three inputs are a logic 1 , and (iii) all inputs are a logic 1 .
