<p>A Hall-effect sensor (300) having a distributed array of current sources (306) connected to an active region (304) formed in a substrate (302) of an integrated circuit. A corresponding array of current sinks (308) is connected to the active region (304) of the substrate opposite the current sources (306). When current flows in a path parallel to a first dimension of the active region (304) from the current sources (306) to the current sinks (308), a measurable Hall voltage develops across the active region (304) if a magnetic field (B) is passed through the sensor. This Hall voltage is measured by two terminals (310, 312) connected across a second dimension of the active region (304) of the substrate. The measured Hall voltage sensitivity is very high according to this configuration. <IMAGE></p> |
