摘要

我们提出了一种磁场传感器的设计和实验表征。该传感器基于霍尔电阻器阵列，并使用横向bjt作为有源元件来读取磁场对其的影响。它的输出是电流模式，而不是更频繁的电压模式。结果表明，原始灵敏度可达5mA/T，无可测量的磁滞。

Design and experimental characterization of a magnetic field sensor

We present the design and experimental characterization of a magnetic field sensor. This sensor is based on an array of Hall resistors and uses lateral BJTs as active elements to read the effect of the magnetic field on it. Its output is in current mode, instead of the more frequent voltage mode. Results show that a raw sensibility of 5mA/T can be achieved, with no measurable hysteresis.
