  • Patent number: 10283559
    Abstract: A pixel arrangement includes a photodiode, a reset transistor configured to be controlled by a reset signal and coupled to a reset input voltage, a transfer gate transistor configured to transfer charge from the photodiode to a node, wherein the transfer gate transistor is controlled by a transfer gate voltage, and a source follower transistor controlled by the voltage on the node and coupled to a source follower voltage. A capacitor is coupled between the node and an input voltage. During a read operation the input voltage is increased to boost the voltage at the node. The increased input voltage may, for example, be one the reset input voltage, said source follower voltage, said transfer gate voltage and a boosting voltage.

  • Publication number: 20110170657
    Abstract: An analog counter includes, for at least one step, an input for receiving electric pulses and a means for modifying, by consecutive increments or decrements, a storage voltage for each received electrical pulse, a means for resetting the storage voltage, and a comparator for comparing the storage voltage with a threshold voltage and adapted to generate exceedance information. The counter further includes a control means adapted to control the resetting means in the event of the simultaneous detection of exceedance information from the comparator and of an input pulse.
