Abstract:
Various embodiments of the present technology comprise a method and apparatus for an encoder. In various embodiments, the encoder is configured to remove impairments from the signals produced by a servo motor and compute a phase that is used to determine the rotary position of the servo motor. In various embodiments, the encoder is configured to remove a DC offset, improve amplitude mismatch, and compute a phase offset.

Claim (Index 15):
A system capable of generating a first signal and a second signal, comprising:\n a motor assembly comprising:\n a motor having a motor position; and \n an optical encoder coupled to the motor and comprising:\n a first correction circuit configured to:\n apply a first gain to the first and second signals; \n apply a first DC offset correction to the first and second signals; \n generate first channel data; and \n generate second channel data; \n \n a second correction circuit coupled to an output terminal of the first correction circuit and configured to:\n apply a second gain to the first and second channel data; \n apply a second DC offset correction to the first and second channel data; \n generate corrected first channel data; and \n generate corrected second channel data; \n \n a signal processing circuit coupled to the second correction circuit and configured to:\n compute a first quadrature of the first signal; \n compute a second quadrature of the second signal; \n estimate a first phase according to the first signal and the first quadrature; \n estimate a second phase according to the second signal and the second quadrature; and \n compute a phase offset based on the first and second phases.
