Abstract
A circuit dedicated to the stabilization of integrated circuit temperature charactristics is achieved by integrating on the same semiconductor material chip as the integrated circuit and a device comprised of a sensor having at least two resistors (R1, R2 and/or R3, R4) supplied between two voltages (DC1, DC2) used alone or in conjunction with differential circuit structure (T2, T3) supplied by a current source (T1), comprising a transistorized variable load impedance (T4, T5, T6, T7). The resistors have different temperature coefficients, and the output voltage (VA or VB) of the bridge is temperature dependent. The integrated must incorporate a voltage-controlled element (transistor or diode).
