Paper Abstract

A new type of series connected double-injection magneto-diode formed on a SOI substrate is designed. This new type of magneto-diode features a considerably high sensitivity in response to a certain change of the magnetic field around it and also has the ability to compensate the excursion caused by the fluctuation of the temperature nearby. Other than the discussion of the structure, sensitivity, and the principle of work about this new magneto-diode, a new type of tachometer circuit based on this kind of magneto-diode that features a desirable stabilization and a relatively high sensitivity and can distinguish phases is designed. This circuit can be used widely to monitor the flux of liquid in many circumstances.
