Integrated system for reading magnetic information |
摘要 |
The invention relates to a system for reading magnetic information, comprising a magnetoresistive bar and a first differential amplifier connected to the magnetoresistive bar. A reading system according to the invention also comprises a second differential amplifier arranged in parallel with the first amplifier, a first capacitor arranged between the first transistor and the magnetoresistive bar, and a second capacitor arranged between the fourth transistor and the bar, and an analog adder combining the output signals of the first and second amplifiers. This structure allows integration of the decoupling capacitors and thus prevents the occurrence of external resistances and inductances which are detrimental to the common-mode reject rate.
