MEMS-based oscillators: a review

MEMS-based oscillators: a review. IIUM Engineering Journal, 15 (1). pp. 1-15. ISSN 1511-788X (2014)


This paper presents an overview of micro electromechanical (MEMS) based oscillators. The accuracy and stability of the reference frequency will normally limit the performance of most wireless communication systems. MEMS technology is the technology of choice due to its compatibility to silicon, leading to integration with circuits and lowering power consumption. MEMS based oscillators also provide the potential of a fully integrated transceiver. The most commonly used topology for MEMS based oscillators are pierced oscillator circuit topology and TIA circuit topology. Both topologies result in very competitive output in terms of phase noise and power consumption. They can be used for either higher or lower Rx. The major difference between both topologies is the number of transistors used. TIA circuit used number of transistors comparatively to pierce circuit. Thus the design complexity of the TIA is higher. Pierce circuit is simpler, provide straightforward biasing and easier to design. The highly integratable MEMS-based oscillators have made them much needed in future multiband wireless system. Hence, the future wireless systems will be able to function globally without facing difficulties.
