Abstract
This paper presents a low-ripple voltage tripler charge-pump intended to provide a stable supply voltage to the cascaded circuits, thus allowing relaxed design specifications of the latter. The structure, which is implemented by means of an array of charge pump modules sequentially enabled, was developed for a phase-change memory (PCM) device, but it is also suitable for use in other applications. The circuit was integrated in a PCM test-chip, fabricated in 0.35-mum CMOS technology. An output voltage ripple of only 16 mV has been experimentally demonstrated
