CMOS jittering time-to-digital converter for biomedical sensors - NIMBO project

In the joint UiO/UCSD - NIMBO project we are developing a body surface, through skin biomarker sensor. The technology is based on microwave sensing where precise measurement of signal time delay is essential.

In this master project you will design and measure a time-to-digital converter focusing on high time resolution. By exploiting the properties of jitter in the time-domain sampler combined with signal averaging, the delay can be measured with a resolution exceeding the unit delay elements used by the sampler.


The system in mind includes a time-to-digital sampler, jitter noise generator and calibration system.  This includes tunability of the jitter generator for different jitter probability distributions. True noise generators are challenging to implement while pesudo-nosie solutions are feasible. A major challenge of this project is analysis of noise properties with respect to implementable tunability of CMOS noise generators.
