A Low-Power Microcontroller in a 40-nm CMOS Using Charge Recycling

A 40-nm microcontroller featuring voltage stacked memory and logic is presented. This involved connecting the power domains of the memory and logic in series, such that the ground of one power domain is connected to the positive supply rail of the other. In this paper, an ARM Cortex-M0+ and its peripherals are powered from 0 V to V<sub>DD<...

Design of a low-cost microcontroller-based lightning monitoring device

Lightning data is not only important for environment and weather monitoring but also for safety purposes. A device that monitors and keeps track of occurrences of lightning strikes has been developed. A communication interface is established between the sensors, data logging circuit and the microcontroller. The digital outputs of the lightning...
