An integrated circuit having a first couple of components R and C, at least a second couple of components R<SUB>1</SUB>-R<SUB>3 </SUB>and C'<SUB>1</SUB>-C'<SUB>2 </SUB>and a calibration circuit. The couple of componets form an RC cell of which one component is adjustable, and the calibration circuit. The invention corrects the errors in the values of the components of RC cells of the same nature. The calibration circuit performs the adjustment of an RC cell and then applies the same correction to the components of the other RC cells of the same nature.
