  • METHOD AND SYSTEM FOR PROCESSING ANALOGUE SIGNALS DELIVERED BY PIXELS
    Publication number: 20260143254
    Abstract: A method for processing an analogue signal is provided. An example includes a method for processing an analogue signal from a pixel using a correlated double sampling method including two successive measurements of durations between the instant of start of a ramp signal and the instant where the pixel signal crosses the ramp. A single counting circuit is used for the two measurements and in particular a single counter that will provide the two counting values used for generating the least significant bits of the output digital word representative of the amount of light captured by the pixel.

  • Device for determining a propagation time
    Patent number: 10868547
    Abstract: The invention concerns a device including: first and second detectors of the phase and/or of the frequency of an input signal with respect to first and second reference signals; and a Sigma/Delta converter interpreting outputs of the first or of the second phase and/or frequency detector to determine a propagation time of the input signal.
