Zusammenfassung:A light sensor includes a light sensing element, a first integrator and a sigma-delta analog-to-digital converter. The light sensing element senses light during a measurement period to generate a first current. The first integrator is coupled to the light sensing element and configured to receive the first current and generates a first integration signal. The sigma-delta analog-to-digital converter is coupled to the first integrator and used to convert the first integration signal to a sensing value.
