Figure P16.53 shows a classic CMOS logic circuit, (a) What is the logic function performed by the circuit? (b) Design the NMOS network, (c) De­termine the transistor W/L ratios to provide symmetrical switching times at twice the switching speed of the basic CMOS inverter with (W/L)n = 2and (W/L)P = 4.
