Power Amplifier Savings with DC-DC Converters in GSM-GPRS-EDGE Mobile Handsets

This article is targeting on a technology of adjustable DC-DC converters, which can be implemented with GSM-GPRS-EDGE power amplifiers, as it is already widely used in CDMA/WCDMA handsets. Simulations show why this has not been used so far and how important the battery average consumption savings could be, with this low complexity technology used instead of a polar-loop architecture, which is under high effort recently in many companies.

Power Amplifier Savings with DC-DC Converters in GSM-GPRS-EDGE Mobile Handsets

In the last decade, mobile phones have become an integral part of our life. Up to one billion new mobile phones are shipped each year by manufacturers. Newly introduced features and smaller form factors of mobiles require less current consumption from a battery. Battery technologies are getting more advanced,...
