Light sensor and sensing method thereof

A light sensor with a high sensitivity includes a light sensing element, a first integrator and a sigma-delta ([Sigma][Delta]) analog-to-digital converter. The light sensing element senses a light during a measurement period and generates a first current. The first integrator coupled to the light se...

Summary:A light sensor with a high sensitivity includes a light sensing element, a first integrator and a sigma-delta ([Sigma][Delta]) analog-to-digital converter. The light sensing element senses a light during a measurement period and generates a first current. The first integrator coupled to the light sensing element receives the first current and generates a first integration signal. The sigma-delta analog-to-digital converter coupled to the first integrator is used to transfer the first integration signal to a sense value.
