Abstract
This paper presents an innovative inverting charge pump on a series-parallel architecture, suitable for ground-referenced power supply systems for earphone audio amplifiers. Implemented in a 40nm CMOS technology, the paper illustrates in details the architecture and the final measurement on silicon, highlighting great performance in terms of efficiency and THD when applied as negative power supply for high quality earphone audio amplifier. © 2011 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
