I'm an undergraduate in Electronic & Telecommunication Engineering at the University of Moratuwa (GPA 3.77/4.0, Dean's List) with a deep focus on analog IC design, integrated photonics, and embedded systems.
Currently a Research Intern at StarLabs, NUS — developing a smart reaction wheel controller for satellite ADCS using advanced FOC algorithms on BLDC motors. Robotics team member at RoboticGen, leading the open-source STM32F405 micromouse to 3 m/s.
My IC work runs on open-source PDK flows: SKY130A (Tiny Tapeout op-amp: 80 dB, 4 MHz, 2 nA disable) and IHP SG13G2 (2.4 GHz Fractional-N PLL + LC-VCO for IEEE CASS UNIC-CASS). Final year project: NS-SAR ADC in Cadence on SKY130.
- Analog & RF IC Design — PLLs, VCOs, op-amps, SAR ADCs on open PDKs (SKY130A, IHP SG13G2)
- Integrated Photonics — PICs, optoelectronics, electro-optic control systems
- Satellite ADCS — FOC-based reaction wheel controller at NUS StarLabs
- Open-Source Silicon — Tiny Tapeout, UNIC-CASS / IEEE CASS programs
- Robotics Hardware — STM32F405 PCB design, PID motion control, encoder feedback
