Quasi-digital front-ends for current measurement in integrated circuits with giant magnetoresistance technology

In this study, the authors report on two different electronic interfaces for low-power integrated circuits electric current monitoring through current-to-frequency (I–f) conversion schemes. This proposal displays the intrinsic advantages of the quasi-digital systems regarding direct interfacing and...
