1. ECE 3130 Digital Electronics and Designby
Priyankar Roychowdhury
Lab 3 Part A
XOR Gate without using MOS
Fall 2017

2. Objective
In this lab, you will learn, if some libraries exist, how to use them to design and simulate a new component

3. Before starting this experiment:
You need to locate your last lab- works on your computer
If you don’t find, copy from your backup source and place those in your documents folder
You need to follow Lab2 partA slides for the process of experimentation

4. What we will do:
We will design XOR gate without any MOS but with existing NOT and NAND gates libraries we did in last lab

5. XOR
Truth table A B
Output 1
Design by NAND Gate:

6. XOR Schematic

7. XOR
Symbol

8. XOR Test circuit schematic Add labels to inputs & output
These labels will help to easily identify signals in simulation waveforms

9. Waveform – XOR

10. Propagation Delay
Now, measure the propagation delays: tPLH and tPHL
