Title: Integrated magnetic sensor
Inventor: HIRATA MASAKI
IPC: H01L43/14
Filed: 1982-07-02
Abstract: PURPOSE:To obtain a sensor which is easy to detect the variation of magnetic field by a method wherein a Hall element having a plurality of pairs of output terminals arranged in proximity each other at the center current terminals, comparators which respectively input a pair of signals, and a means to detect the variation of state of the comparators are equipped. CONSTITUTION:A Hall element 1 has current terminals 2 ane 3 and the pairs of output terminals 4,5,6,7, and 8,9. When a current (i) is supplied to the current terminals 2 and 3, and a magnetic field B is vertically impressed. Hall electromotive force generates at the output terminals. The voltage difference proportional to the impressed magnetic field is generated between the pair of output terinals 4 and 5, and this voltage is inputted to the comparator 10 and then amplified to logical level. The output of an OR circuit 19 turns a logical high voltage, when at least one of the comparators 10-12 varies in state. If there is a comparator which has a logical low voltage at the initial state and has an off-set voltage sufficiently lower than signal voltage, the state of the comparators varies, resulting in the detection of magnetism at the time of impressing the magnetic field.
