Abstract
A 30.0-dBm polar digital power amplifier (PA) is
implemented based on a switched-capacitor PA (SCPA) and
multiple efficiency-enhancement techniques, such as Class-G,
Doherty, and time interleaving (TI). The PA demonstrates six
efficiency peaks and seamless efficiency curves between the peaks
in the power back-off (PBO) reg ion with the three efficiency-
enhancement techniques. For the implementation of the efficient
and linear Class-G technique, a linear single-supply current-reuse
Class-G switch is p
