Efficiency and linearity multicontact hall plates

WITHIN THE LAST YEARS significant attention has been given to the application of the Hall effect. After the semiconducting compounds with high carrier mobility InSb and InAs were developed, it was possible to produce Hall generators giving a power of some 100 mw to the load of the Hall circuit. The usual arrangement shown in Figure 1 with two current contacts and two Hall contacts does not satisfy all requirements of efficiency power output and linearity for applications as gyrators, isolators or multipliers. The use of multicontact Hall plates, increases the power output and the efficiency, and decreases the multiplication errors.
