This research laboratory was established to investigate various aspects of VLSI circuits and systems design. Specifically we are interested in design of energy efficient digital circuits and systems, circuits for nano-CMOS and beyond, VLSI architectures and algorithms for signal processing and communications, and power electronics. Current research activity includes:

  • Energy Efficient Digital Systems and Power Electronics:   This is an ongoing investigation in which techniques are being developed for lowering power dissipation in circuits and systems without drastically affecting performance. With the ever growing popularity of battery powered portable applications like personal communication systems, mobile computing, etc., energy efficient, high performance circuits are gaining importance. Investigation is being carried for developing power management and energy efficient circuits. Efficient control methods for power converters and other areas of power electronics are also being explored.  

  • Circuits and Systems for Signal Processing and Communications: This activity involves developing VLSI algorithms, architectures and circuits for digital signal processing, and wireless communications. This research leverages past background in energy efficient, digitally intensive mixed-signal design techniques to develop circuits and systems for these applications suitable for implementation in nano-CMOS technologies. Projects include, All-digital PLL (ADPLL), envelope tracking for efficient power amplifiers, etc.  

  • Circuits using MEM/NEM Relays: This investigation involves the use of micro/nano-electromechanical (MEM/NEM) relays in conjunction with CMOS technology to design novel digital and mixed-signal circuits. Work is under way to design innovative digital and power management circuits by exploiting interesting switching characteristics of these relays.

  • Reconfigurable Digital Systems: This investigation involves design and development of reconfigurable hardware that is suitable for DSP and multimedia applications. Rapid prototyping of wireless communication systems and sensor network platform is also being investigated. Several building blocks for power aware digital filters and communication algorithms are being developed.
