Although quartz crystals have served as temperature sensors, designers haven’t taken advantage of the technology because few manufacturers offer the sensors as standard products (references 1 and 2).

Since quartz resonators have a relatively larger mass, they also may experience fractures under very high shock levels. Figure 2 compares phase noise for MEMS and quartz crystal oscillators.

The article also reviews several recently proposed alternatives to quartz crystals and describes their key properties, such as ceramic resonators and CMOS resonators. Introduction From the early days ...

Founded in 1954 and located in Whitby, Ontario, Quantic Croven is a leading manufacturer of precision AT, FC, IT, and SC-cut quartz crystal resonators for mission-critical applications. WHITBY, ON ...

SiTime XCalibur active resonators provide 10x better reliability than quartz, making them ideal for automotive and industrial applications that demand robustness and long life in harsh environments.

Figure 3 shows a 3D view of the 550 by 450 by 200 mm 3 resonator with WLP. To put things in perspective, diced WLP pMEMS resonators were placed on a grain of rice (Fig. 4).

New levels of precision control over the quantized energy levels of mechanical resonators have been achieved by teams in the US and Switzerland, who independently measured the number of phonons in a ...
