• Low Voltage Circuit Design
• Low Power Circuit Design

Experience

• Oct 2004 - Dec 2004 : Did extensive measurements and modelling of a weak inversion MOS varactor for use in 0.5V active-RC filters.
• Apr 2004 - Sep 2004 : Did tests and measurements on the 5th order active RC elliptic filter (designed in March 2004), with PLL, at a 0.5V power supply.
• Jan 2004 - Mar 2004 : Designing a 5th order active RC elliptic low pass filter at a 0.5V power supply. Design specifications are geared towards a GSM filter.
• Aug 2003 - Dec 2004: Did tests and measurements of the opamp circuits (designed in Jul 2003).
• Jun 2003 - Jul 2003: Designed an 0.5V power supply opamp in a 0.18µm CMOS process. This scheme used bulk driven transistors.
• Jan 2003 - Jun 2003: Designed another 0.5V power supply opamp in a 0.18µm CMOS process. nMOS and pMOS bodies were forward biased to artificially lower the V_T of the transistors.
• Sep 2002 - Dec 2002 : Did further research on low power opamp-less filter design techniques.
• Summer 2002: Interned at Microsemi Corp. at Carlsbad, California. Did extensive tests and measurements on the previously designed Audio Delta Sigma Converter and an Audio Class D Amplifier.
• Sep 2001 - May 2002: Research on a low power opamp-less filter-design technique.
• Summer 2001: Interned at Microsemi Corp. at Carlsbad, California. Worked on a digital Delta Sigma Modulator. This was a part of a bigger Delta Sigma modulator to be used for hearing aids.
  • Pending patent on a coding scheme for a two bit delta sigma modulator serial interface which saves power.
• Jan 2001 - May 2001: System level research on Delta Sigma Modulator Architectures.
• July 1999 - May 2000: Indian Institute of Technology, Madras, India: Design of a Piezo-electric SAW motor and its drive circuitry.
