Abstract:
1. A transistor arrangement with temperature compensation, comprising: at least one transistor comprising a control input, a controlled path, and at least one adjustable geometric parameter; a temperature measuring means configured to output a temperature-dependent signal; a control unit configured to set the at least one geometric parameter of the transistor based on the temperature-dependent signal; and a comparator coupled to the control unit, and comprising inputs configured to receive a temperature-independent signal and the temperature-dependent signal, wherein the at least one transistor comprises a plurality of partial transistors each connected in a series circuit with an assigned switching transistor, wherein the series circuits each comprise a partial transistor and a switching transistor, and wherein each of the series circuits are connected together in parallel with one another, and wherein the switching transistors each have a control input coupled to the control unit.
