High-efficiency hybrid EER transmitter using optimized power amplifier
FREE-DOWNLOAD I Kim, YY Woo, J Kim, J Moon… – Microwave Theory and …, 2008 – This paper describes a new design approach for a power amplifier (PA) of the highly efficient hybrid envelope elimination and restoration (H-EER) transmitter. Since the PA operates mostly at the average power region of the modulation signal, power-added efficiency
A fully-integrated quad-band GSM/GPRS CMOS power amplifier
FREE-DOWNLOAD I Aoki, S Kee, R Magoon, R Aparicio… – Solid-State Circuits, …, 2008 Abstract—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 net- works on the same silicon
A 5.8 GHz 1 V linear power amplifier using a novel on-chip transformer power combiner in standard 90 nm CMOS
FREE-DOWNLOAD P Haldi, D Chowdhury, P Reynaert… – Solid-State Circuits, …, 2008 A fully integrated 5.8 GHz Class AB linear power amplifier (PA) in a standard 90 nm CMOS process using thin oxide transistors utilizes a novel on-chip transformer power combining network. The transformer combines the power of four push-pull stages with low insertion loss […]
