Classification: CPC H  G | IPC G  H

Claim 14:
15. An imaging system comprising:
a semiconductor device comprising a single-photon avalanche diodes; and
control circuitry configured to:
set a bias voltage for the single-photon avalanche diode to a first voltage level;
while the bias voltage is at the first voltage level, generate data using the single-photon avalanche diode for a given exposure;
set the bias voltage for the single-photon avalanche diode to a second voltage level that is different than the first voltage level; and
while the bias voltage is at the second voltage level, generate additional data using the single-photon avalanche diode for the given exposure, wherein the single-photon avalanche diode comprises an anode coupled to a first voltage supply terminal, a cathode, and quenching circuitry coupled between the cathode and a second voltage supply terminal, wherein setting the bias voltage for the single-photon avalanche diode to the first voltage level comprises providing the bias voltage to the second voltage supply terminal at the first voltage level, and wherein setting the bias voltage for the single-photon avalanche diode to the second voltage level comprises providing the bias voltage to the second voltage supply terminal at the second voltage level.
