  • Systems and methods for low power time-domain measurement of complex impedance
    Patent number: 9575105
    Abstract: Various embodiments of the invention enable low-power accurate measurement of complex impedance at a range of frequencies of interest to determine a frequency response of a test sample. The system requires only a few external precision components that are not integrated into a microprocessor, thereby, providing a low-cost alternative to existing designs. In certain embodiments, low-power operation is accomplished by utilizing a simplified digital signal processing scheme that requires only a small number of ADC samples. Measurement accuracy is achieved by a digital conversion to baseband that does not suffer from channel matching issues and by utilizing a single analog path.

  • Method and apparatus for controlling a continuous time linear equalizer
    Patent number: 8588288
    Abstract: An example method for controlling a continuous time linear equalizer includes: developing a voltage histogram of a signal present at an output of a continuous time linear equalizer; developing a quality factor for the voltage histogram; comparing the quality factor with a prior quality factor; decreasing an equalization of the continuous time linear equalizer if the quality factor is less than the prior quality factor and increasing the equalization of the continuous time linear equalizer if the quality factor is greater than the prior quality factor.
