Abstract

A switch-mode regulator and a class-AB buffer in parallel function as a PA supply modulator and achieve 10MHz bandwidth and 2mV ripple. The resulting modulator is suitable for CDMA applications. High-frequency switch-mode regulator ripple is cancelled by a rail-to-rail class-AB amplifier. The combined regulator tracks the input signal envelope with less than 0.2% error and achieves a maximum efficiency of 82% with a bandwidth of 10MHz.
