MEMS technologies alleviate many limitations of quartz-based frequency-control designs, but the integration of MEMS into frequency-control and clock products is still characterized as a two-chip solution and a reliance on boutique MEMS foundries. The recent introduction of CMEMS technology builds upon the benefits of MEMS solutions by processing the resonator directly on top of an advanced mixed-signal IC to provide true CMOS+MEMS integration. Learn why monolithic integration is more important now than ever to frequency control and how it suggests an irreversible trend for new functionalities and technologies in the timing industry.
