Abstract
A single-package bridge-type magnetic-field angle sensor comprising one or more pairs of magnetic tunnel junction sensor chips rotated relative to each other by 90 degrees in order to detect two magnetic field components in orthogonal directions respectively is disclosed. The magnetic-field angle sensor may comprise a pair of MTJ full-bridges or half-bridges interconnected with a semiconductor package lead. The magnetic-field angle sensor can be packaged into various low-cost standard semiconductor packages.
