Abstract:
A radio frequency (RF) power amplification system in which a combination of a linear voltage regulator having a PFET pass device and a DC-DC converter having an NFET pass device is used to supply power to an RF power amplifier. The RF power amplifier receives power from either the linear voltage regular and its associated PFET pass device or the DC-DC converter and its NFET pass device, depending upon the condition of a mode signal.
