ABSTRACT:
A voltage/voltage converter for integrated circuits is characterized in that it presents a multistage symmetrical structure and comprises at least one input stage constituted by a clock booster circuit (CB) of symmetrical structure which delivers two output voltages, a voltage multiplier stage of symmetrical structure comprising two voltage multiplier circuits (CMi; CMip) respectively connected in two branches (B1; B2) of the converter and having applied respectively thereto the output voltages from the first stage, and an output stage (S) constituted by a multiplexer circuit (MX) having applied thereto the two output voltages from the voltage multiplier stage. The invention is particularly applied to EEPROMs and to low-voltage integrated circuits.
