Abstract: A temperature sensor comprising at least one temperature sensing circuit. Each temperature sensing circuit comprise a series connection of a first connecting node, a first capacitor connected to a first reset transistor for biasing the first capacitor to a first bias voltage, a bias transistor for distributing charges between the first and second capacitor after biasing the first and second capacitor, a second capacitor connected to a second reset transistor for biasing the second capacitor to a second bias voltage, a second connecting node. Each temperature sensing circuit comprises at least one voltage readout node between the first capacitor and the second capacitor.
