摘要：883,096. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A. G. July 24, 1958. No. 23902/58. Class 37. The magnetic effect on the wafer produced by the control current in a Hall generator is eliminated either by an additional compensating winding or by a split feed arrangement. Fig. 2 shows a Hall modulator having control current electrodes 5 and 6 and Hall electrodes 7 and 8. A compensating loop 9 is connected via a potentiometer 10 to the control current supply whereby the magnetic field on wafer 4 due to the control current path may be compensated. In Fig. 3 the control current is fed to electrode 5 by two leads 15 in parallel, and potentiometer 13 provides for adjustment so that the magnetic effects of the two leads compensate each other.
