CPC H03K 17/969 (2013.01) [H03K 17/04123 (2013.01); H05B 45/00 (2020.01)] | 20 Claims |
1. A circuit comprising:
a plurality of light emitters connected between a first node and a second node;
a plurality of capacitors, wherein each capacitor in the plurality of capacitors corresponds to a respective light emitter in the plurality of light emitters; and
a pulse-control switch connected to the plurality of light emitters,
wherein, during a first period, the pulse-control switch restricts current flow and each capacitor in the plurality of capacitors is charged via the first node,
wherein, during a second period, one or more capacitors of the plurality of capacitors are discharged, and
wherein, during a third period, the pulse-control switch allows current flow that discharges one or more undischarged capacitors of the plurality of capacitors through one or more corresponding light emitters of the plurality of light emitters, thereby causing the one or more corresponding light emitters to emit respective pulses of light.
