A solid-state image sensor for detecting one or more photons includes a plurality of pixels sensitive to such photons, each of the pixels having a logic unit and an avalanche photodiode operatively connected to the logic unit, the logic unit being configured to provide an electrical signal different from the electrical signals provided by the logic units of the remaining pixels. The logic unit of each of the pixels is operatively connected to the logic unit of an adjacent pixel, such logic unit outputting the electrical signal when the avalanche photodiode belonging to the same pixel and the avalanche photodiode belonging to such adjacent pixel each detect at least one photon within a time window.

A power supply circuit module for a TDC (Time to Digital Converter) includes a first input for receiving a control signal, a second input for receiving a power supply voltage, and an output configured to be connected to the power supply input of the TDC. An active main power supply device is configured to receive the control signal at the input and to contribute on the value of the power supply voltage resulting at an output by a voltage value lower than a first predefined percentage with respect to the nominal power supply voltage. A number N of active secondary power supply devices each are configured to contribute on the value of the power supply voltage resulting at the output by a percentage different from the remaining active secondary power supply devices.
