The Boolean function for a carry-out signal of a one-bit full adder is given by

(a) Design an NMOS logic circuit with depletion load to perform this function. Signals A, B, and C are available, (b) Assume ( W/L)L = 1, VDD = 5 V, VTNL = -1.5 V, and VTND = 0.8 V. Determine the W/L ratio of the other transistors such that the maximum logic 0 value in any part of the circuit is 0.2 V.
