Abstract :
A 100 MHz DC-DC switching converter with one-cycle control is proposed for radio frequency power amplifier. All blocks of one-cycle controller are built up on AMI 0.5 mum technology. The power supply has a tracking bandwidth of 5 MHz and an estimated efficiency of 80%. The converter performance is verified by means of simulations.
