Split-Array, C-2C Switched-Capacitor Power Amplifiers

This paper presents a 13-b C-2C split-array (SA) multiphase switched-capacitor power amplifier (SAMP-SCPA) implemented in 65-nm CMOS. The SAMP-SCPA was designed for 16-b resolution to offer extra states for linearization/calibration using digital pre-distortion (DPD). Resolution limits for SA SCPAs...
