ImageAssistant Professor, Department of Electrical Engineering, IIT-Jodhpur
Thesis Title: Semiconductor Ring Laser Gyroscopes - Modeling, Design and Critical Performance Limiting Parameters
In this thesis, SRLG has been mathematically modeled using rate equations of counter-traveling electric fields inside the gain medium and the resonant cavity. In order to identify the critical performance limiting parameters and phenomena, every metric of SRLG such as quantum limit, angle random walk, scale factor stability, null shift and lock-in threshold have been thoroughly modeled in terms of material, geometry and environmental parameters. effects of nonlinearities such as spatial hole burning, mode coupling, gain saturation etc. on the SRLG sensitivity have been evaluvated. The critical performance affecting parameters are identified and optimized to achieve best possible performance

Vasu Pulijala, PhD Graduate

ImageAssistant Professor, Department of Electrical Engineering, NIT, Nagpur
Thesis Title: CMOS RFIC Inductors Incorporated with Domain Patterned Permalloy Films and Investigation of Domain Dynamics therein
This area dealt with incorporation of domain controlled magnetic material with Radio Frequency On-chip Inductors for RFIC applications. Introduction of magnetic material with inductors is a classic effort done from years to reduce the size, recently it was found that, mere incorporation does not work at high frequencies and a detailed study needs to be done to pin-point the reason. This work was based on finding out exact reason why the material does not work at high frequencies and what needs to be done to improve the frequency response. This work provided solution for this problem and a boost in inductance upto 200% at high frequencies were achieved. The fabrication and measurement work was done with the help of IISc-Bangalore.

Image Thesis Title: CDesign and Equivalent Circuit Modeling of Miniature Slotted RFID Tag Antennas for Metallic Applications
This thesis was based on reduction of size of RFID Antennas. As the frequencies at which RFID communication is done are lower compared to Mobile Phones etc, the antenna sizes tend be larger. The reduction of size was achieved by adding slots and increasing thickness of existing antenna. A reduction of 50% was achieved. In addition, a model was also proposed to help future designers. The fabrication and measurement work was done with the help of IIT-Kanpur.

Mohd. Anwar, MS Graduate

Image Thesis Title: Novel Noise Cancelling Technique for CMOS Low Noise Amplifier
This thesis was based on Design of UWB LNA with a constant Low noise in the whole band. The work was implementation of communication algorithm on noise cancelation in RFIC LNA. The fabrication and measurement work was done with the help of IIT-Hyderabad.

Ahsan, MS Graduate

Image Thesis Title: Multiprocessing on FPGA using Light Weight Processor
This work showcases how to develop a multiprocessing system on FPGA using multiple light weight soft processors (LWP). These processors take very less resources, consume less power and are high in performance. They make use of abundantly available hardened DSP48 blocks on the FPGAs to extract performance and also provide 2nd level programmability to the designer. The processors can also work in conjunction with a custom hardware to achieve much higher system performance.
