CMOS Integrated Power Amplifiers for RF Reconfigurable and Digital Transmitters

Abstract This dissertation focuses on three different efficiency enhancement methods that are applicable to handset applications. These proposed designs are based on three critical requirements for handset application: 1) Small form factor, 2) CMOS compatibility and 3) high power handling. The three presented methodologies are listed below:

1) A transformer-based power combiner architecture for out-phasing transmitters

2) A current steering DAC-based average power tracking circuit for on-chip power amplifiers (PA)

3) A CMOS-based driver stage for GaN-based switched-mode power amplifiers applicable to fully digital transmitters

This thesis highlights the trends in wireless handsets, the motivates the need for fully-integrated CMOS power amplifier... (more)
