The NAND and the negative-OR symbols represent equivalent operations, but they are functionally different. For the NOR symbol, look for at least one HIGH on the inputs to give a LOW on the output. For the negative-AND, look for two LOWs on the inputs to give a HIGH output. Using these two functional points of view, show that both gates in Figure 3-88 will produce the same output for the given inputs.

Draw and design a logic circuit that implements the given expression using 6 NMOS devices only. Draw the logic gates diagram first. Use 2-input logic gates only.
