AMPLIFYING DRIVING UNIT USING GIANT MAGNETO RESISTANCE SENSOR AND DIAGNOSIS DEVICE USING THE SAME |
摘要 |
The present invention relates to an amplifying unit comprising: a pull up down unit pulling up or pulling down a positive GMR signal and a negative GMR signal provide by a GMR sensor; a GMR amplifying unit including a plurality of amplifying units generating a GMR signal by amplifying a difference between the stand-alone type signal and the negative GMR signal according to the GMR sensor; a low pass filtering unit attenuating noise of the GMR signal; a reference converting unit generating a reference voltage having a predetermined range for generating a GMR signal; and a gain converting unit amplifying the GMR signals inputted to the plurality of amplifying units by several ten or hundred times. |
