Projects

RF frequency and hardware

• Designed low noise amplifier (LNA) with sub-180nm COMS in Cadence, which provides a variable forward gain of 5 - 20dB for 1.5 GHz, 2 GHz and 3 GHz signals from a 2.5 V power supply.

Noise Figure is less than 7dB in all cases. The power consumption is about 90mW.

Communication Systems

• Built two digital receivers in MATLAB to process DTV and WCDMA signals.

• Built WCDMA transmitter in MATLAB, which generates single/multi codes of WCDMA signals.

RF frequency filter design

• Passive delay equalizer in Hspice. Zero Frequency Envelop Delay is 325 pSec with 2% tolerance. Driving Point Input Impedance is 50 Ohms. Magnitude Response Flat to 3 dB through at least 15 GHz.

Mixed-signal IC design

• Design a two stage low power operational Amplifier in Cadence. Voltage gain is 75 dB. Unity gain bandwidth is 100 MHz, slow rate is 50 V/us and output swing is 1.6 V.

Digital system design

• 16 X 16 bit multiplier in VHDL to implement an audio Graphic equalizer on Spartan II FPGA.

• Blackjack game in VHDL on the Altera EPF10KLC84-4 FPGA chip.

Network and communication

• Implemented a C++ program to simulate a race among 4 cellular units to find their way with the help of 2 base stations and reach a target before running out of battery or going out of range. All communications take place over TCP and UDP sockets in client-server architecture.
