Abstract:
Provided are a method and system for digitizing a sensor model output signal. The system includes a filter, a demodulator coupled to the filter, a DC offset cancellation mechanism coupled to the demodulator, and an analog to digital converter (ADC). The ADC is directly coupled to the demodulator and the DC offset cancellation mechanism.
