—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 outphasing signal processing functions. The chip is(More)
As the resolution of electrical ADCs gets limited at higher sampling rates due to sampling clock jitter, low-jitter mode-lock laser based photonic ADCs are starting to gain more attention. As well as low-jitter and high-linearity operation at very high speeds, photonic ADCs provide the opportunity to de-multiplex electrical signals to enable the parallel(More)
