| Abstract: | A novel magnetic-field sensitive switch is presented.The part of magnetic-field sensor has a magnetic-field sensitive device with complement triple-drain MOS transistor.The magnetic-field sensitive switch is integrated with the constant current source,amplifier circuits,Schmitt trigger and output driver transistor on a same chip.The switch has the advantage of good stability,high magnetic sensitivity,low power consumption,anti-interference and so on.The single-ended output sensitivity is 4 V/T.Due to adopting standard CMOS process,it is easy to produce. |
