Projects and course work:

Prototype of industrial standard conveyor belt:

Designed the prototype conveyor belt using DC motor with 100% duty cycle, this was achieved using STM32F407VG microcontroller and PWM, used H-bridge to reverse the direction of belt.

Sensed temperature of the conveyor using LM35, ADC, DAC, SPI module and displayed it on to a LCD. Transmitted sensor data through CAN bus interface between two microcontroller boards.

Used IAR Embedded Workbench IDE and C to develop firmware for the prototype. MEMS based actuator for medical puncture devices:

Designed Opamp 741 at transistor level using EDNMOS technique, designed layout in Mentor Graphics and unidirectional actuator using silicon on glass technique and fabricated the dyes.

Used CoventorWare to design and simulate the actuator, performed finite element analysis to determine the stress handling capability of the actuator.

Tested both dyes using Semiprobe’s probe station by measuring the change in capacitance between the fingers of proof mass and fixed fingers of the actuator. 4X4 bit Register ALU using CMOS technology:

Designed static RAM cell, basic gates (and, or, not, Nand, nor, Xor), buffer cells, multiplexers and delays at transistor level. Designed layouts and schematics using Mentor Graphics.

Simulated the above design using Eldo and Zelga simulators to perform timing analysis, performed DRC and LVS checks using IC station.

Tested the design by performing binary math operations like addition and subtraction on the data stored in the designed registers, demonstrated read and write cycles of the design. Design and Simulation of DC-DC (Fly-back) converter:

Designed Fly-back converter, functions in both continuous and discontinuous conduction mode,.

Determined the Turner’s ratio of the fly-back transformer, Magnetizing current, current in the windings and analyzed power loss of the transformer and converter.

Incorporated voltage clamp snubber, designed the snubber-using resistor, capacitor and a diode. Simulated Fly-back converter in OrCAD Pspice 9.1.

Speed detection of vehicles using Frame Subtraction technique:

Recorded a video of a moving car using Sony handycam at 30 frames per second, processed this video using MATLAB 2013 to extract individual frames.

Converted the extracted frames to greyscale for noise reduction, subtracted the greyscale frames to determine the change in pixels corresponding to the car.

Determined the speed of the vehicle and displayed it on the output window of MATLAB. Parameter Extraction of Silicon using Hall Effect and Vander Pauw technique:

Established Ohmic contacts with silicon using silver paint, designed a mesh to deposit aluminum contacts, Calibrated Keithley 181 and 220 Nano voltmeter and Programmable current source.

Designed and 3D printed holders for magnets using AutoCAD used these in the process and successfully demonstrated Hall Effect.

Academic Coursework:
