  • Abstract In recent years, electronic products became portable and have lowered power consumption because of the limited energy resource availability. The measurement of energy consumption of these devices is important for benchmarking and testing.
    This study describes a battery emulator that measures the energy consumption of a circuit under test (e.g. ASIC) using an energy measurement circuit and a microcontroller. The microcontroller allows any battery voltage to be emulated dynamically via a digital-to-analog converter, depending on the loading evaluated from energy measurement and from the datasheet representing an emulated type of battery. Furthermore, the system emulates a condensed battery lifetime so that the measurement time is reduced. Using a battery emulator in testing saves time and cost compared with a using real batteries. The system changes between two measurement ranges depending on the magnitude of the detected current. National Instruments LabVIEW software and DAQ was used to measure the result. Evaluation is presented which shows a current measurement range from 0.3 nA to 2 µA and an emulated battery voltage between 0 V and 4.0 V.
