Abstract
An adjustable impedance boosting circuit comprises a differential pair of gain stage transistors. A magneto-resistive element may be coupled to the emitters of the gain stage transistors, and a collector load may be coupled to a collector of at least one of the gain stage transistors. The invention further comprises a variable impedance load coupled in parallel with at least a portion of the collector load, the variable impedance load operable to adjust the impedance of the boosting circuit in proportion to the resistance of the magneto-resistive element.
