摘要： The invention concerns a circuit whereof the operational speed varies according to temperature, supply voltage and the intrinsic quality of the circuit transistors, associated with a compensating circuit comprising a constant current source (26) supplying a substantially constant current independent of temperature, voltage supply and the intrinsic quality of the circuit transistors, a variable current source (28) supplying a current which increases in inverse proportion with temperature, supply voltage and the intrinsic quality of the circuit transistors, and means for decreasing the circuit operational speed when the difference in the currents produced by the first and second sources increases.
