—Concentric distributed active transformers (DAT) are used to implement a fully-integrated quad-band power amplifier (PA) in a standard 130 nm CMOS process. The DAT enables the power amplifier to integrate the input and output matching networks on the same silicon die. The PA integrates on-chip closed-loop power control and operates under supply voltages(More)
ACKNOWLEDGEMENTS First of all, I would like to acknowledge the guidance, support and patience from my advisor Prof. David Rutledge. His knowledge and wisdom have guided me in my research; his continuous support and encouragement have helped me through many challenging situations. I appreciate this wonderful opportunity to study and work in the MMIC group at(More)
Abstruct-A 250 W dual-band power amplifier belonging to the Class E/F switching amplifier family is presented. The amplifier operates in the 7 MHz and 10 MHz HAM bands, achieving 16 dB and 1 5 d B gain with power added efficiencies (PAE) of 92 70 and 87 % in those bands, respectively. It utilizes dual-resonant passive input and operation at both frequencies(More)
