摘要

由于无线和移动应用电路的极低功耗要求的出现，移动通信的研究和开发目前正在显着增长。在这种电路中，还需要监测进出电池的电流。对于GSM应用，该电流可高达2A。我们提出了一种低偏置电流检测放大器，可以检测低至10mA的电流。

A chopper-based, CMOS current sense amplifier for power management applications in mobile communications

Mobile communications research and development is presently in significant growth, due to the advent of the very low power consumption requirement in wireless and mobile application circuits. In such a circuit there is an additional need to monitor the current that flows from and to the battery. This current can be as high as 2A for GSM applications. We present a low-offset current sense amplifier that can allow sensing of currents as low as 10mA.
