PROBLEM TO BE SOLVED: To accurately detect the difference between two peak values from the difference of values when the two peak values are held. SOLUTION: In a magnetic field detection device, in the first state, a gate terminal of a first transistor TR1 is connected to a first terminal 139. A source terminal of the first transistor TR1 is connected to an input part 146 of a first hold part 145. A gate terminal of a second transistor TR2 is connected to a second terminal 141. A source terminal of the second transistor TR2 is connected to an input part 148 of a second hold part 147. In the magnetic field detection device, in the second state, the gate terminal of the first transistor TR1 is connected to the second terminal 141. The source terminal of the first transistor TR1 is connected to the input part 148 of the second hold part 147. The gate terminal of the second transistor TR2 is connected to the first terminal 139. The source terminal of the second transistor TR2 is connected to input part 146 of the first hold part 145. COPYRIGHT: (C)2004,JPO
