  4. Abstract:
  5. Internet of Things (IoT) devices have strict necessity for power consumption in order to achieve expected battery life. IoT nodes feature extreme power consumption range over 100 dB, between their operating modes. The main focus of this paper is to design and implement a high precision, high dynamic range, low power, and flexible power measurement system, which can be applied to different applications. The proposed system consists of a voltage regulating control loop, zero offset amplifiers, high precision analog to digital converters, and reference voltage. The proper operation of the proposed circuit are verified numerically with simulations and experimental measurements. The implemented system features maximum sampling rate of 5 MHz, load regulation error of 0.16%, and linearity error of 0.32%. It is expected that the proposed system provides clear information of power behavior of IoT devices, which can be used for network's power optimization as well as a self-power test equipment. © 2019 Elsevier Ltd
