摘要： A temperature sensor (300) comprising at least one temperature sensing circuit (100). Each temperature sensing circuit (100) comprise a series connection of a first connecting node (111), a first capacitor (110) connected to a first reset transistor (120) for biasing the first capacitor to a first bias voltage, a bias transistor (140) for distributing charges between the first and second capacitor after biasing the first and second capacitor, a second capacitor (150) connected to a second reset transistor (160) for biasing the second capacitor to a second bias voltage, a second connecting node (151). Each temperature sensing circuit comprises at least one voltage readout node between the first capacitor (110) and the second capacitor (150).
