In a conventional noise measurement the detector is connected remotely to the source of the fluctuations, which makes it difficult to achieve reliable measurements at high (> 1 GHz) frequencies. On the contrary, using an on-chip noise detector, high frequencies are naturally available. Yet there is a caveat: in an on-chip detection scheme it is more difficult to distinguish the properties of the noise source from those of a tiny near-by detector. In this project methods of direct on-chip detection of noise are developed and discussed.
Richard Deblock and Helene Bouchiat participated in the ULTI meeting in April 2006. The project planning was initiated and different realizations of on-chip detection of high frequency noise, utilizing the knowledge of both the Paris and the Helsinki groups.
