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 65 nm CMOS technology, the paper illustrates in details the architecture and the final measurement on silicon,...
A filterless class-AB/D audio power amplifier integrated into a feature-rich 2.5G/3G baseband processor in standard 65-nm CMOS technology is designed for direct battery hookup in mobile phone applications. Circuit techniques are used to overcome the voltage limitations of standard MOS transistors for operation at voltage levels of 2.5-4.8 V. Both amplifiers can drive more than 650 mW into an 8-??...
