Patent ID: 7266002

Claim:
A voltage/voltage converter for integrated circuits, the converter presenting a symmetrical multistage structure and comprising at least one input stage constituted by a clock booster circuit (CB) of symmetrical structure which delivers two output voltages, a voltage multiplier circuit of symmetrical structure comprising two voltage multiplier circuits (CM i ; CM ip ) respectively connected in two branches (B 1 ; B 2 ) of the converter and having the output voltages of the input stage applied respectively thereto, and an output stage (S) constituted by a multiplexer circuit (MX) having the two output voltages from the voltage multiplier stage applied thereto, the converter being characterized in that each voltage multiplier circuit (CM i ; CM ip ) is controlled by a control circuit (CC i ; CC ip ), and in that each voltage multiplier circuit (CM i ; CM ip ) supplies voltages needed both for the operation of its own control circuit and for the operation of the control circuit of the other voltage multiplier circuit of the same stage.
