Abstract

Temperature sensor having a resistor arrangement (R1, HL) which contains at least one temperature-dependent resistor (HL) and is connected to a voltage supply (+Ub-Ub), having a first amplifier circuit (V1), which is connected on the input side to the resistor arrangement (R1, HL) and on the output side to a first measuring and evaluating circuit (M1 + A1), and having a second amplifier circuit (V2), which is compensated for frequency response, and is connected on the input side via a high-pass circuit (C1, R4) to the resistor arrangement (R1, HL) and on the output side to a second measuring and evaluating circuit (M2 + A2). <IMAGE>
