Low-Power Crystal and MEMS Oscillators: The Experience of Watch Developments by Eric VittozEnglish | PDF | 2010 | 219 Pages | ISBN : 904819394X | 4.11 MB
Electronic oscillators using an electromechanical device as a frequency reference are irreplaceable components of systems-on-chip for time-keeping, carrier frequency generation and digital clock generation. With their excellent frequency stability and very large quality factor Q, quartz crystal resonators have been the dominant solution for more than 70 years. But new possibilities are now offered by micro-electro-mechanical (MEM) resonators, that have a qualitatively identical equivalent electrical circuit.
