High-Throughput Signal Component Separator for Asymmetric Multi-Level Outphasing Power Amplifiers

This paper presents an energy-efficient high-throughput and high-precision signal component separator (SCS) chip design for the asymmetric-multilevel-outphasing (AMO) power amplifier. It uses a fixed-point piece-wise linear functional approximation developed to improve the hardware efficiency of the...
