Abstract
Apparatus for producing an electrical signal that is indicative of a temperature is disclosed, the apparatus comprising: a first thin-film transistor TFT comprising a first source, a first gate and a first drain, the first drain being configured to receive a reference current; and a second TFT comprising a second source, a second gate and a second drain, the first and second gates both being configured to receive the same gate voltage, wherein the first and second TFTs are configured such that a temperature dependence of the first TFT differs from a temperature dependence of the second TFT, such that an output current at the second TFT and the second drain is dependent on temperature. The temperature dependence of the output current can be controlled by selecting suitable design parameters for the first and second TFTs. A method of designing the apparatus to produce an output current with a target temperature dependence is also disclosed.
