Spread Spectrum Trims EMI in MEMS Oscillators (.PDF Download)

Electronic timing functions are traditionally provided by oscillators based on quartz-crystal resonators, although microelectromechanical-systems (MEMS) oscillators are being applied more often in applications once dominated by quartz-crystal oscillators. MEMS oscillators use mechanical structures, such as miniature tuning forks, to achieve resonant frequencies. MEMS devices are fabricated from silicon semiconductor materials and can be made smaller and operate with less power consumption
