A high sensitivity integrated switched Hall sensor based on CSMC 0.5 μm CMOS technology is introduced.The sensor consists of a cross-shaped Hall device and a signal conditioning circuit dynamic offset cancellation technique.By optimizing the structure of Hall device and applying a novel signal conditioning circuit
the sensor achieves a high sensitivity.TCAD simulation and Cadence circuit simulation show the sensor can detect minimum magnetic field of 2 mT and output standard digital signal under 3 V working voltage.Meanwhile
the offset voltage of more than 6 mV inside Hall device can be effectively cancelled.
