摘要：

A new class of integrated magnetic sensors, a magneto-operational amplifier (MOP) is presented. The MOP is a universal magnetic sensor which can be used for many purposes. The principle of the MOP is a feedback amplifier similar to the usual operational amplifier which is widely used for realizing any analog function. In order to make use of the advantages of an operational amplifier, the MOP has similar components: a differential amplifier stage which includes a magnetic detector; a sufficiently large gain amplifier; and an output stage. By changing external feedback elements, the MOP can realize various magnetic operations, such as a linear magnetic sensor, a magnetic switch, a magnetic filter, etc. In this paper experimental results of some applications of the MOP are given. © 1990.
