摘要：An optical analog to digital converter including a light source, a driver, an arrayof single photon avalanche diodes, and control circuitry. The light source emits photons.The driver receives an analog input signal and to drive the light source on the basis of the
analog input signal. The array of single photon avalanche diodes detects the photonsprovided by the light source. The control circuity is coupled to the array of single photonavalanche diodes and activates the array of single photon avalanche diodes for apredetermined time interval such that the array of single photon avalanche diodesdetects the photons provided by the light source during the predetermined timeinterval. The control circuity further determines the number of single photon avalanchediodes of the array of single photon avalanche diodes which detected a photon duringthe predetermined time interval.
