dc.description.abstract | Modern Internet-of-Things (IoT) devices and sensor systems exhibit extreme dynamic current consumption profile, since latest microprocessors and electronics support ultra-low currents in the sleep phase, of only a few nA, while they expend several mA in the active state. Existing power meters are incapable of measuring their expenditure in order to aid the development of energy-efficient schemes. In this work we introduce the eProfiler, a novel in-situ system for measuring the power expenditure of sensing devices that illustrate a wide current range. Our meter features an autoranging shunt-resistor switch that supports ultra-fast alternations of 6ns, formed with the aid of high-speed comparators, that can successfully adapt to any sharp transition. Moreover, a high-speed Analog-to-Digital Converter (ADC) with multiple inputs is employed to simultaneously monitor the shunt-resistors, delivering a speed of 150 kSamples/s at 16 bit resolution. The proposed meter can be leveraged for the real-time, as well as the long-term monitoring of IoT devices with its cost being less than 90 euros. Furthermore, the proposed system can actuate or trace state alternations on I/O pins with a maximum delay of 2 µs, in order to provide correlation capabilities with the obtained power measurements. The eProfiler features a wide dynamic range of 1.000.000:1 while also being able to monitor currents of a few nA. The average obtained error of the meter is 0.45 %, with a maximum error of 1.6 %. © 2020 ACM. | en |
