The first prototype of an eXtra Small Atomic Resonator (XSAR) was presented by CSEM in 2009. This paper describes the progress realized in 2010 towards the realization of a low-power miniature atomic clock. We present a second prototype as well as the first RF frequency and laser locked loops fully integrated on a chip.
This paper explores the use of MEMS devices such as bulk acoustic wave (BAW) and low frequency silicon resonators, in combination with digital circuits and techniques, to reach miniaturization and low power dissipation in a 2.4 GHz transceiver targeting wireless body area networks (WBAN) and wireless sensor networks (WSN) applications. Precise phase locking of the BAW digitally controlled oscillator...
This paper explores where MEMS devices such as BAW and low frequency silicon resonators can be used to reach further miniaturization and to lower the power dissipation of 2.4GHz transceivers targeting BAN and WSN applications. The system requirements for improving such networks are derived after analyzing appropriate low power communication protocols. A super-heterodyne transceiver architecture taking...
