Abstract:
In a semiconductor device, a sine wave signal is input to a first input part and a cosine wave signal is input to a second input part. A multiplexer alternately selects one of the sine wave signal and the cosine wave signal. An analog to digital converter converts the output signal of the multiplexer into a digital value. A switching circuit is coupled between at least one of the first and second input parts and the multiplexer. The switching circuit is configured to be able to invert the input sine wave signal or the input cosine wave signal, in order to reduce the angle detection error due to the non-linearity error of the A/D converter.

Claim (Index 12):
A motor control device for controlling the drive of a synchronous motor based on an output signal of a resolver coupled to the synchronous motor,\n wherein the resolver outputs a first signal indicating the sine of an angle to be detected as well as a second signal indicating the cosine of the angle, wherein the motor control device comprises: an inverter circuit for generating a motor voltage supplied to the synchronous motor; a resolver to digital converter for calculating the angle based on the first and second signals; and a processor for generating a control signal to control the inverter circuit based on the calculated angle, wherein the resolver to digital converter includes: a first input part to which the first signal is input; a second input part to which the second signal is input; a multiplexer for selecting one of the first and second signals; an analog to digital converter for converting the output signal of the multiplexer into a digital value; and a switching circuit coupled between at least one of the first and second input parts and the multiplexer, wherein the switching circuit is configured to be able to invert the input first or second signal.
