Abstract :
The design considerations for a 2 MHz synchronous buck converter for a cellular phone RF power amplifier supply are presented. Particular emphasis is placed on the problems associated with achieving this high switching frequency with a current-mode architecture and in an inexpensive 0.5 μm CMOS process.
