Quartz crystals have dominated the timing market for the last 70 years. FBAR technology is poised to replace quartz for many high frequency applications. Integration of the ultra-small form factor of the microcap’d FBAR into the SoC BGA packages currently in the market will make these applications earn the moniker, "Crystal-less". To replace crystals for non-GPS applications, the FBAR must demonstrate superb aging properties, repeatable and well-behaved temperature stability, immunity to…

A comparison of FBAR oscillators with standard resonators and stress relieved resonators

One of the issues facing many types of oscillators is the transference of stress from the external world through the die to the resonator. Typically, resonators are clamped at more than one location.
