Abstract

PURPOSE:To make possible magnetism detection with high accuracy completely eliminating the effect of temperature, by giving a certain temperature coefficient to voltage supply of a bridge type magnetism detection circuit including a magnetoresistance element. CONSTITUTION:A bridge circuit 2 is formed by crossing four thin film stripes 1a-1d at right angles in the direction of stripe. Between the circuit 2 and a constant voltage power source 3, a temperature compensation circuit 4 consisting of resistors (R1), (R2) and a transistor 4 are provided. By this construction of the magnetism detector circuit, a temperature coefficient of the voltage supply to the circuit 2 is easily and optionally obtained by the resistors (R1), (R2). A temperature coefficient of a formula 1 is given to the voltage Ein when R1 and R11 are the resistance of the thin film stripe under the magnetic fields parallel to, and crossing at right angle with, the direction of the current flows in the thin stripe, and the temperature coefficients are (a) and (a'). The effect of temperature is thus completely eliminated.
