Abstract
The present invention provides an inductive angle sensor with improved common mode noise rejection and a signal processing method of the same, which can improve electromagnetic compatibility (EMC) characteristics and obtain an accurate output value by eliminating common mode noise. The signal processing method includes adding signals obtained from a pair of receiver coils by an adder, subtracting the signal obtained from one of the pair of receiver coils from the signal obtained from the other receiver coil by a subtracter, multiplying the value obtained from the adder by the value obtained from the subtracter by a first multiplier, multiplying the value obtained from the subtracter by itself by a second multiplier, and dividing the value obtained from the first multiplier by the value obtained from the second multiplier by a divider.
