Digital vs. Analog

The real-world signals are analog. However, processing, communicating, and storing data in digital form is advantageous over analog form. Therefore, the analog signal is converted to digital form at the transmitter end and again converted back to analog form at…

What are Test Chips in VLSI

A test chip is a small-scale integrated circuit that is specifically designed for testing purposes, feasibility checks and performance analysis. It serves as a platform for evaluating the functionality of individual circuit blocks, testing the reliability of manufacturing processes, and…

Introduction to Digital Electronics

Electronic circuits can broadly be divided into two broad categories: Analog – involves quantities with continuous values Digital – involves quantities with discrete values Some advantages of digital over analog are as below: Efficient processing and reliable transmission Easier storage…

What is MPW in VLSI

MPW stands for Multi-Project Wafer, which is a cost-effective way to prototype integrated circuits. In an MPW, multiple projects share a single wafer during the fabrication process, which enables lower costs by spreading the cost of the wafer among multiple…

ASCII Code

ASCII codes are alphanumeric codes that represent numbers, alphabets, symbols and special characters in computers. ASCII stands for American Standard Code for Information Interchange. Whenever we press a key from the keyboard, the corresponding ASCII code goes into the computer.…

What is a Wafer in VLSI

A wafer is a thin slice of semiconductor material, typically made of silicon, that serves as the substrate for the fabrication of integrated circuits in the field of VLSI. During the fabrication process, the wafer undergoes a series of processes…
