    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).

    摘要： There is provided an apparatus (100) for sensing the temperature of an object. The apparatus comprises a sensing element (110) to be inserted into or placed adjacent to the object, the sensing element comprising a resonant circuit (112), and the resonant circuit having a temperature-dependent resonant frequency and comprising a capacitor (114). The apparatus further comprises a detection unit (120) configured to interface with the resonant circuit to receive a response associated with a current resonant frequency of the resonant circuit, and a control unit (130) configured to determine the current resonant frequency of the resonant circuit based on the received response, and to determine the temperature of the object based on the determined current resonant frequency of the resonant circuit. The sensing element and the detection unit are physically unconnected.
