Question 16.DA.12: A STATIC CMOS LOGIC GATE Objective: Design a static CMOS log...


Objective: Design a static CMOS logic gate to implement a specific logic function.

Specifications: A static CMOS logic gate is to be designed that implements the function of a three-input odd-parity checker. The output is to be high when an odd number of inputs are high. The size of each transistor is to be determined so that the switching speed is the same as that of a basic CMOS inverter with W_{n} = W and W_{p} = 2  W . A minimum number of transistors are to be used in the NMOS pull-down and PMOS pull-up portions of the circuit.
Choices: We will assume that input signals A, B, and C as well as the complements \bar{A}, \bar{B}, and \bar{C} are available.
