Universidad de Zaragoza (orcid)0000-0001-5402-1251 Analysis of mismatch impact on image rejection ratio for passive polyphase filters 2018 Access copy available to the general public Unrestricted Passive polyphase filters (PPFs) are useful symmetric RC networks for processing analog quadrature signals. Passive polyphase filters are also used to implement differential-quadrature or quadrature-differential converters. The quality of these quadrature signals is essential to achieve good performance in modern communication systems. However, mismatch effects can produce notable degradation in the PPF frequency response, and this results in an important reduction in quadrature signal quality, being amplitude balance and phase offset notably affected. Both these errors could be summarized and evaluated together considering image rejection ratio as a figure of merit. This work deepens in the analysis of mismatch impact on PPF, studying image rejection ratio degradation for 2 PPF types, and a systematic method is proposed to obtain the worst case of mismatch in PPFs with any number of stages. It has been validated in a 65-nm CMOS technology. info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2014-52840-R info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2017-85867-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 1.554 2018 ENGINEERING, ELECTRICAL & ELECTRONIC 172 / 265 = 0.649 2018 Q3 T2 0.331 2018 Applied Mathematics 2018 Q2 Electronic, Optical and Magnetic Materials 2018 Q2 Electrical and Electronic Engineering 2018 Q2 Computer Science Applications 2018 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Aznar, F.
