近年來因為能源愈來愈不足夠，導致晶片以及各項研發的方向愈來愈趨於低功耗，可攜帶式，不外乎是為了在這個能源枯竭的時代減少資源的消耗以及節省成本。
本文介紹一種基於微電流量測為基礎，加上微控制器的編譯，進而達到晶片功耗測量的功能；除此之外，利用微控制器的編譯，只要取得任何種類電池的放電曲線，就可以藉由Datasheet的內容，依實際的負載動態模擬各式電池的輸出，甚至可以按自己需要的比例將整個電池的放電時間縮短，將原本很長時間的放電曲線，按比例縮短成需要的時間，藉此節省實際測量晶片功耗或任何種類的負載所需的能量。將固定能源的利用達到最大化，藉此省去購買實體能源的費用，例如電池。另外，此系統可以依據輸入的電流大小的不同，靈活的切換電容值，增大可量測的電流範圍，且調整至誤差最小的範圍。
本系統主要使用Microcontroller和DAC, integrator組成並利用Cadance的Specture以及Synopsys的Hspice做模擬，並且使用National Instruments的LABVIEW做輸出結果，紀錄工作並利用matlab做輸出結果的分析。

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.
