Abstract
A light sensor circuit, which comprising a photodiode and a voltage follower. By setting the voltage follower to reduce the influence from the junction capacitance of the photodiode, a required time of a repeat integration module will not be influenced by the photodiode to efficiently keep the performance and the accuracy of the analog to digital converting device when the light sensor circuit is used to the analog to digital converting device in repeat operation.
