Abstract:This paper presents a CMOS RF/DC current-mode detector as an essential requirement to realize Built-in Self Test (BiST) and calibration functionalities for current-mode based RFICs and demonstrates its application on the calibration of a current-driven passive mixer. A method is presented to extract test friendly DC features from the RF signal, without deteriorating the performance of test blocks in the transceiver. Simulation performance with IBM 90-nm process using 1.2 V power supply shows that the proposed … 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.
