Research Project Title:
Molecular Clock: Ultra-Stable Frequency Reference On A CMOS Chip
abstract:Frequency references based on molecular transitions have the potential to reach parts-per-trillion accuracy. Such precise references have wide application in devices that require exact timing such as GPS satellites and receivers. For my project, I will work on characterizing and improving a next generation frequency reference centered on a carbonyl sulfide molecular transition. The project will involve testing the stability of the reference as well as its temperature sensitivity. A microcontroller-based circuit that senses the environment temperature and correspondingly adjusts the output frequency will then be made in order to reduce the circuit’s temperature dependency.
I am participating in SuperUROP to gain research experience in electrical engineering as well as experience working with integrated circuits. I took 6.775, CMOS Analog and Mixed Signal Design, last year, as well as many other circuits classes. I hope to learn how to apply the knowledge I gained from these classes to real world problems.
