Abstract: The present application relates to a method for operating sensing signals and the circuit thereof. An analog-to-digital converter first processes the input signal having the most significant bit (MSB DATA) data at least once. Afterwards, the analog-to-digital converter processes the input signal having the least significant bit (LSB) data and the MSB data and sums all the input signals. Thereby, the process steps of the analog-to-digital converter can be simplified and the processing time can be shortened.

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.
