  • Metastability error reduction in asynchronous successive approximation analog to digital converter
    Patent number: 9621179
    Abstract: Various aspects facilitate error reduction for an analog to digital converter (e.g., due to metastability). A digital to analog converter generates a scaled reference voltage based on a reference voltage. A comparator component performs a comparison between an input voltage and the scaled reference voltage based on a defined period of time to perform the comparison.

  • Gain calibration by applying a portion of an input voltage to voltage associated with a capacitor array
    Patent number: 9602119
    Abstract: Various aspects facilitate gain adjustment associated with an analog to digital converter. A capacitor array comprises a plurality binary-weighted capacitors and generates an output voltage received by a comparator based on an input voltage and a reference voltage. A gain calibration component receives the input voltage and applies a modified input voltage that corresponds to a portion of the input voltage to the output voltage generated by the capacitor array component.

  • Image-canceling quadrature modulator and method
    Patent number: 7139326
    Abstract: Canceling images in a quadrature modulator includes frequency shifting the baseband signal and images; filtering the frequency shifted baseband signal and images; phase and frequency shifting the baseband signal and images; filtering the phase and frequency shifted baseband signal and images; combining the filtered frequency shifted baseband signal and images with the filtered phase and frequency shifted baseband signal and images to suppress the negative frequency images and isolate the modulated baseband signal.
