Abstract
There is provided a near-zero-power wakeup system in which a MEMS sensor for mechanical or acoustic signals is coupled to a very-low-power complementary metal oxide semiconductor (CMOS) application-specific integrated circuit (ASIC). Power consumption can be minimized by operating the ASIC with sub-threshold gate voltages.
