Abstract
The invention relates to a circuit of which the operating rate varies according to temperature, supply voltage and intrinsic quality of the transistors of the circuit, associated to a compensating circuit which comprises a constant current source ( ) that produces a substantially constant current which is independent of temperature, supply voltage and intrinsic quality of the transistors of the circuit, a variable current source ( ) producing a current that increases in an inverse proportion to temperature, supply voltage and intrinsic quality of the transistors of the circuit, and means for decreasing the operating rate of the circuit when the difference of the currents produced by the first and second sources increases.
