In accordance with an embodiment of the present invention, a resolver
system has at least one resolver and at least one amplifier in electrical
communication with each resolver. A reference circuit is in electrical
communication with the amplifiers. The reference circuit provides
reference signals to the amplifiers. A non-linearity calibration and
compensation circuit in communication with each amplifier uses the
amplified reference signals to provide scale factors, so as to enhance a
precision of the resolver system.
