摘要： A resolver arrangement that is inexpensive and yet offers high resolution and high noise rejection includes a carrier signal generator and two processing channels each of which has an analog input connected a different one of the stator coils and a channel output. Each of the processing channels includes a sigma-delta modulator with an output that supplies a bit-stream representative of an analog input signal received from a respective stator coil. Each channel also includes a first digital filter that receives the bit-stream from the sigma-delta modulator and converts the bit-stream to intermediate digital data-words. In addition, each channel has a digital synchronous demodulator that demodulates the intermediate digital data-words in synchronism with the carrier signal providing demodulated data-words. Finally, each channel has a second digital filter that averages the demodulated data-words and supplies digital output data-words on the channel output, the carrier signal being suppressed in the output data-words.

摘要： Successive approximation register (SAR) analog-to-digital converters (ADCs) generally employ capacitive digital-to-analog converters (CDACs) to perform data conversions. In these CDACs, matching of capacitive values is important, and for conventional high resolution SAR ADCs, complex trimming or calibration procedures can be too costly. Here, however, a SAR ADC is provided that performs error correction so as to reduce the overall cost compared to conventional SAR ADCs.
