Abstract:
A sensor circuit may include one or more feedback loops to process and attenuate ripple and/or a test signal. The sensor circuit may comprise at least one magnetic field sensing element to generate a magnetic field signal representing a magnetic field to be measured, a test signal generator circuit configured to generate a test signal and combine the test signal with the magnetic field signal to generate a combined signal, and a signal path for processing the combined signal. The signal path may comprise an amplifier circuit to amplify the combined signal, an analog-to-digital converter (ADC) to convert the combined signal to a digital combined signal, and a feedback circuitry coupled to receive the digital combined signal and extract the test signal. A test comparator circuit compares the extracted test signal to a reference signal.

Claim (Index 13):
The sensor circuit of  claim 11  wherein the second feedback circuit comprises:\n a demodulator to demodulate a signal from the ADC in a digital domain by inverting a bit stream of the signal from the ADC according to a frequency chopping rate;\n a digital integrator configured to integrate an output signal of the demodulator to form an integrated signal; and \n a digital-to-analog converter (DAC) configured to convert the integrated signal to an analog signal and provide the analog signal to the chopper-stabilized amplifier circuit.
