A temperature-reliant monolithic circuit that brings about a change of the outgoing current when the temperature if the substrate increases. It contains a constant voltage source consisting of three transistors (Q1, Q2, Q3) and resistances (R1, R2, R3). The difference in the base emitter voltage drop in two of the three transistors (Q1, Q2) is multiplied upwards and obtained as a temperature-reliant voltage drop over a resistance (R3). The base of a transistor (Q5) is connected across this resistance conducting the outgoing current. The change in the substrate temperature affects the conductivity of this transistor so that the temperature-reliant voltage drop interacts with the change in the conductivity of the transistor (Q5).<IMAGE> |
