Abstract: An output circuit for a single-photon avalanche diode. In some embodiments, a system includes: a first sensing element; a bus line; a first pull-down circuit; a first pull-up element; and a second pull-up element, the first pull-up element, the second pull-up element, and the first pull-down circuit being connected to the bus line, the first pull-down circuit being connected to the first sensing element and configured to be activated based on a signal from the first sensing element, the first pull-up element having a lower drive strength than the first pull-down circuit.
