  • Continuous time ADC and filter
    Patent number: 9344107
    Abstract: The invention concerns an analog to digital conversion and filtering circuit comprising: an input for receiving an analog input signal; an asynchronous continuous-time analog to digital converter adapted to generate, based on the analog input signal, a digital continuous-time signal; a feedback path comprising a digital continuous-time filter adapted to generate a filtered signal to be combined with the analog input signal, the digital continuous-time filter being adapted to generate the filtered signal by: filtering out at least one first frequency range of the digital continuous-time signal; and amplifying at least one second frequency range of the digital continuous-time signal.

  • Systems and methods for implementing error-shaping alias-free asynchronous flipping analog to digital conversion
    Patent number: 9300315
    Abstract: A programmable, quantization error spectral shaping, alias-free asynchronous analog-to-digital converter (ADC) is provided. The ADC can be used for clock-less, continuous-time digital signal processing in receivers with modest Signal to Noise-plus-Distortion Ratio (SNDR) requirements and a tight power budget.
