Abstract—A fully integrated switched-capacitor power amplifier
(SCPA) utilizes switched-capacitor techniques in an EER/Polar
architecture. It operates on the envelope of a nonconstant envelope
modulated signal as an RF-DAC in order to amplify the signal
efficiently. The measured maximum output power and PAE are
25.2 dBm and 45 %, respectively. When amplifying an 802.11g
64-QAM orthogonal frequency-division multiplex
