Nano Device & Integrated System Development Lab Click here for more details

Traditionally integrated circuits have been developed using schematics. With shrinking silicon structures and higher integration densities, automated tools for Electronic Design Automation (EDA) have been developed.

The Nano-Devices and Integrated Systems Development Lab is a part of the Department of Electronics & Communication Engineering ECE at Narula Institute of Technology in Kolkata. We conduct in depth research in various aspects of Nanoelectronics, Nano devices, VLSI Circuits and MEMS.

This lab has been established to give idea to the students & researchers of Electronics & Communication Engineering, those who would like to develop themselves in the configuration and simulation of Very Large Scale Integrated Circuits & Systems, Nano device simulation & design parameter extraction & System programming for the embedded systems.

In this laboratory there is provision to configure and simulate CMOS Circuit & Systems using Mixed signal design methodology. It is possible to design of layout of various CMOS Circuits in micron, submicron and deep submicron level using Tanner Tools & CADENCE.

Also it serves as a guide to make it understood the complete process to work through in designing onto Programmable logic devices like that is CPLDs and FPGAs, right from the simulation (zero delay to the implementation aspects).

The Spice Simulation of different types of complex digital & analog circuits and Circuit Layout design of different types of digital & analog circuits using EDA Tools (i.e. TSPICE, CADENCE) will be carried out. The complete FPGA design process, including adding timing constraints, pin assignment, synthesis, placement & routing, bit-stream generation, will be carried out.

This Lab helps to reduce uncertainties by providing knowledge as well as efficient software development and system integration. To fabricate and characterize the circuits, we have world class PCB Design facilities.

EDA software (tools) can be used to solve the problems encountered during synthesizing, analyzing, verifying and testing a design. We are seeking more powerful algorithms for solving these problems to minimize chip size and power consumption while optimizing chip performance.

Currently, we especially focus on developing algorithms and methodologies for low-power, timing performance, and manufacturing yield optimization. We also have a strong academic program in the post-graduate and doctoral level.

The field of Advance Communication & Digital Signal Processing (DSP) has seen explosive growth during past three decades, in terms of phenomenal advances and attainments, both on research and applications fronts.

The spectrum of signals that can be processed and analyzed ranges from simple coded text/documents treated as images, presentations enriched with graphics and animation, through speeches and audio to color images and real life high definition videos. Analyzing biological, industrial, metallographic signals leads to decisive and diagnostic knowledge, convertible to intelligent systems capable of predictions and estimations in the relevant field.

Processing involves novel algorithmic development for enhancing the quality of acquired signals and compactly coding the same for efficient storage and bandwidth optimized long-haul communication.

Analysis involves intense mathematical modeling of signals and systems that leads to recognition, classification and conclusions. Examples of socially relevant real life applications that deploy signal processing and analysis are Biometric person authentication, Diseases diagnosis, Speech to text / Braille Conversion for dumb / deaf and visually impaired population, Content based high definition video communication, Vehicular sensor network and intra vehicle signal processing for passenger safety, automatic surface inspection for fault detection in automated manufacturing processes, to mention a few.

The Advanced Communication & Signal Processing Lab is a part of the Department of Electronics & Communication Engineering (ECE) at Narula Institute of Technology in Kolkata. We conduct in depth research in various aspects of Advanced Communication & Signal Processing.

In this lab we study the latest communication techniques.

The optical fiber communication technique is one of the developments in the field of communication where the information is transmitted from one place to another through optical fiber in the form of light defying the electromagnetic interference and increasing the bandwidth. Apart from this satellite communication and mobile communication is the fastest growing segment of the communication industry.

The satellite communication is where artificial satellites are launched in the orbit and are used for various applications of telecommunication, the First generation (1G) cellular systems in the U.S called the Advance Mobile Phone Service (AMPS), used FDMA and the second generation (2G) digital systems called GSM 1. The GSM standard uses a combination of TDMA and slow frequency hopping with frequency-shift keying for the voice modulation.
