  • Channel sensitivity matching
    Patent number: 11630130
    Abstract: A sensor includes: a reference magnetic field generator configured to generate a reference magnetic field that is modulated at a first frequency, a first magnetic field sensing element that is configured to generate a first internal signal that is modulated at a second frequency, and a second magnetic field sensing element that is configured to generate a second internal signal that is modulated at the second frequency. A first amplifier is configured to receive the first internal signal and output a first amplified signal; and a second amplifier is configured to receive the second internal signal and output a second amplified signal. A gain adjustment circuit is configured to produce a gain adjustment signal and adjust a gain of at least one of the first amplifier and the second amplifier based on the gain adjustment signal.

  • Tracking analog-to-digital converter with adaptive slew rate boosting
    Patent number: 11218161
    Abstract: A tracking ADC with adaptive slew rate boosting can dynamically adjust one or more of its operational parameters in response to detecting a slew rate limit condition. In some embodiments, slew rate boosting can include increasing the value of a digital error signal in response to detection of a slew rate limit condition. In other embodiments, slew rate boosting can include increasing a clock frequency of the tracking ADC in response to detection of a slew rate limit condition.
