Abstract
The invention relates to an integrated circuit including impedances having precise values. To compensate for process variations and drift in impedances, the circuit includes automatic control means (3) to adjust the value of impedances (R) to a value that is a function of that of a reference impedance (Rc) external to the integrated circuit.
