LIST OF SOME IMPORTANT PROJECTS WITH SYNOPSIS
SOFTWARE
CMOD
A User friendly Software was developed for different kinds of modualation(amplitude, frequency and phase) to predict the output
from a modulator. User can enter the frequency , amplitude and phase of the carrier and base signal and can choose the type of
modulation. The predicted output will be shown graphically. This software will be very useful in knowing the nuances of
modulation. C languge was used for coding and hence named CMOD.
ONLINE SHOPPING MALL
An Online shopping mall was developed and launched, which contain the product details, checkout carts and a message board.
User can check in and browse through the products , checkout and pay online. They can also create personal account .Active
Server Pages(ASP) was used at the backend to communicate between server and user and Oracle database was used to store all
the information. This project was a success as it never crashed.
HARDWARE
TIMER
A time dependent sound producing device was designed and built. Main component used was TIMER IC 555 which controls the
time intervals of the device. The output of the timer was connected to a speaker and the "ON" time can be controlled by
controlling the input of the timer. This project was done in sophomore year and worked well as expected.

CMOS RF FRONT END RECEIVER FOR BLUETOOTH DEVICES
Complementary Metal Oxide Semiconductor(CMOS) provides low cost single chip devices that are efficient both in space and
function. Bluetooth is an emerging technology that attracts major companies. We designed an RF front end receiver for bluetooth
devices which containes LNA(Low noise amplifier), Voltage Controlled oscillator(VCO) and phase locked loop. Due to time
constrains, we could simulate only the VCO and it worked to perfection. Cadence software was used to design and simulate.
MICROWAVE FILTER DESIGN
Using MATLAB , Microwave filters were designed based on given specifications. The specifications include the filter order, cut
off frequency, passband ripple factor , stop band attenuation. MATLAB program on giving the required specifications calculates
the inductance and capacitance values required for the circuit, plots the amplitue response and group delay of the filter. The code
was tested with different samples to test the effeciency and worked out to be perfect.
DESIGN AND SIMULATION OF PLANAR INVERTED F-ANTENNA(PIFA) FOR MOBILE FREQUENCIES
PIFA finds major use in mobile communication because of its low profile and high effeciency. It occupies less space and hence
can be used alongside the PCB board of the cellphones. A new design was designed and tested for the PIFA configuration to
make them work in three different frequencies ie 0.9/1.8 & 2.4GHz.Shorts and slots were placed at appropriate places to decrease
the length and meander the current respectively. Design was successfully simulated in IE3D 9.0, and electromagnetic solver
using method of moments, for all the frequencies. Due to time constraints, the design could not be built practically.
