MEMS Oscillators: Enabling Smaller, Lower Power Wearables

All electronic products require one or more timing devices depending on the processor, partitioning and various functions in the system. Traditionally, 32.768 kHz crystals and low power MHz quartz-based oscillators have been used for implementing clock functions in battery-powered electronic systems. A new class of low current, low frequency 1 Hz to 32.768 kHz MEMS oscillators now offers advantages over the ubiquitous 32 kHz crystal clock. Small size and low power are critical in IoT applications and wearable devices. Cost is also an important factor as many wearables fall into the consumer category. Innovation in MEMS timing technology is making significant contributions to space and power savings in new wearable applications, as well as improving reliability and costs.
