ABSTRACT:
A charge pump includes a plurality of stages connected in series between a reference potential and an output terminal of the charge pump. The plurality of stages includes a first group of stages, proximate to the reference potential, and a second group of stages proximate to the output terminal of the charge pump. Each stage of the first group includes a pass-transistor with first and second terminals respectively connected to an input and an output of the stage, and a first capacitor with a first plate connected to the output of the stage and a second plate driven by a digital signal switching between the reference voltage and a positive voltage. Each stage of the second group includes a junction diode having a first electrode connected to an input of the stage and a second electrode connected to an output of the stage, and a second capacitor having a first plate connected to the output of the stage and a second plate driven by a digital signal switching between the reference voltage and the voltage supply.
