M.Tech Project Summary:

Title : Design of High-Speed Current-Steering Digital to Analog Converter

Organisation : ANURAG (DRDO), Hyderabad

Tools : Cadence & Matlab

Description

A CMOS current-steering DAC is the usual choice for high speed applications. Design of 12-bit, 2 GS/s 4:1 MUXDAC targeted for DDFS (Direct Digital Frequency Synthesis) systems. This IC is being designed using UMC 0.13-µm CMOS technology. The required output sine wave is stored in a RAM table as a sine function in digital form The RAM's digital sine output is converted to an analog sine wave by a DAC. The steps seen at the DAC output are filtered by a low pass filter to provide a clean sine wave output. The frequency of the sine wave depends on the rate at which addresses to the RAM table are changed.

The low clock LCLK and 4 data channels A<0:11>, B<0:11>, C<0:11>, D<0:11> are using LVDS Rx which works at 500 MS/s. The LCLK clock is used to latch the 4 input data channels at 500 MS/s. Then, one of the four channels is selected using a 4:1 MUX which works at 2 GS/s. This DAC utilizes segmented current source architecture of 8 MSB and 4 LSB to reduce the glitch energy and achieve good linearity. DAC differential outputs are terminated on 50Ω resistors to get a differential output swing of 1V. INL and DNL are measured using Matlab simulations.

Mini projects in M.Tech

Design of 26T full adder layout using tanner tools

UART (Universal asynchronous receiver & transmitter)

Tools : Xilinx 8.1, ModelSim 6.0

Description

Most computers and microcontrollers have one or more serial data ports used to communicate with serial input/output devices such as keyboards and serial printers. By using a modem connected to a serial port, serial data can be transmitted to and received from a remote location via telephone lines, the serial communication interface, which receives and transmits serial data.

B.Tech Project Summary:

Title : Speed Limit Alert

Role : Team leader

Team Size : 5

Description

This circuit has been designed to alert the vehicle driver that he has reached the maximum fixed speed limit. It estimates the necessity of looking at the tachometer and to be distracted from driving.

To achieve this we have used various sensitive components like trimmer resistors, miniature inductance, LEDs, piezo-sounder etc., CA3140 is used here which acts differential amplifier amplifying the electro magnetic signals sensed by miniature inductance earlier. IC LM339 is used to reduce the noise present in the amplified signal. IC 4098 provides the required time delay to display the sensed signal. Its outstanding feature lies in the fact that no connection is required from circuit to engine.
