ABSTRACT:
A circuit for increasing the stability of a sawtooth signal in regard to thermal drift comprises a conventional generator whose output is controlled by a loop circuit constituted by a switch controlled in opposition with respect to a switch connected in shunt on an integration capacitor, a low-pass filter having a cut-off frequency determined to select substantially the d.c. component and an operational amplifier network for determining the gain of the loop circuit which consequently produces a voltage corresponding to the mean value of the signal. The direct-current voltages and the passive components are so determined that the mean value of the sawtooth signal preferably corresponds to the reference zero potential.
