A differentially coupled series inductor for differential RFICs

초록

In this work, we propose a differentially coupled series inductor for RFIC-matching networks. The proposed inductor is designed to reduce the chip area and to enhance the inductance. If a series inductor is required in differential RFICs, two bulky inductors should be implemented. The overall chip size thereby increases considerably. The proposed differentially coupled series inductor can be used instead of two series inductors in a differential RFIC. The size of the proposed inductor is less than half that of two conventional spiral inductors. From the measured results, the feasibility of the proposed differentially coupled series inductor is successfully proved. (c) 2015 Wiley Periodicals, Inc.
