A novel system for amplitude measurement in Giant Magneto-Impedance (GMI) sensors has been developed. It combines a high-speed limiting amplifier with an artful use of feedback. The resulting device is a very efficient detector that allows measuring signals of amplitude as low as few tens of millivolts and of frequency as high as few tens of megahertz. A key advantage of this new concept is that the...
A new design of a High Frequency (HF) current source for GMI magnetic sensors is presented. In this design, a Direct Digital Synthesizer (DDS) is coupled to a current pump to form a voltage-controlled current source. This source is capable of supplying HF currents (with optional DC level) with constant amplitude for a reasonable range of GMI load impedances and for frequencies up to more than 10 MHz...
