Abstract:This paper presents a highly linear and wideband transimpedance amplifier (TIA) suitable for 5G Sub-6 GHz surface acoustic wave (SAW) filter-less receivers (RX). It is known that for the baseband TIA in a SAW-less RX, the high out-of-band (OOB) linearity is necessary to cope with huge OOB blockers. In other words, the input impedance (Z in ) of the TIAs should be as low as possible, which in turn necessitates high-gain, large-bandwidth (BW) operational transconductance amplifiers (OTA). In this work, a pseudod… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
