Abstract
This paper presents a fully integrated Ground Referenced Power Management Unit, made up of two linear voltage regulators and a regulated charge pump providing symmetrical power supply system for the earphone audio amplifier. Embedded in a CODEC for mobile phone application and implemented in a 65nm CMOS technology, the paper illustrates in details the architecture and the final measurement on silicon, highlighting great performance for a high quality earphone audio amplifier successfully validated on silicon. © 2010 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
