The Internet of Things has a specific requirement for low power solutions for high performance applications. Moortec’s 40nm PVT monitoring subsystem is specifically tailored for ultra-low power (ULP) applications such as detectors, sensors, actuators and LED lights. In order for all these levels of IoT related technologies to be optimized and therefore run reliably and within a safe operating environment it is essential to monitor their key metrics such as die temperaturevoltage supply and process variation.
