Claim 0:
1. A measurement circuit configured to provide a torque reading to a motion controller, the measurement circuit comprising:
an offset controller configured to read a temperature signal and to generate an offset voltage in response to reading the temperature signal;
an amplifier configured to read a differential voltage from a differential sensor and to receive the offset voltage from the offset controller, to add the offset voltage to the differential voltage after applying an analog gain to the differential voltage to generate an adjusted voltage, and to transmit the adjusted voltage; and
a temperature sensor configured to transmit the temperature signal indicative of a temperature of the differential sensor, wherein the temperature sensor is configured to output the temperature signal as a digital temperature signal and the offset controller is a digital-to-analog converter configured to convert the digital temperature signal to an analog voltage offset indicative of a temperature of the differential sensor.
