Abstract

PURPOSE: To smooth the output through polarity inversion via the low pass filter, by polarity inversion of the input signal to be converted into magnetic field in about 50% of duty ratio and also by the polarity inversion of the output voltage at the output side of the Hall element in about 50% of duty ratio.
CONSTITUTION: The signal 30a fed to the input terminal of the Hall element 31 is the control current as (a). The input signal 30b is the current as (b) by turning on and off of the switch 35, and this current is converted into the magnetic field B with the core 34. While time t1, the switches 35b, 35c and switches 36b, 36c are closed and the switches 35a, 35d and 36a, 36d are opened, then the voltage at the Hall output terminal 37 is the sum of the Hall output voltage VH and the unbalanced voltage VHO as (c). At time T2, the switch is inverse as at time t1. As a result, the magnetic field B is also inversed to be -VH+VHO. The output after the inversion circuit 36 is (d) and it is smoothed.
