CMOS Active Inductor: A Technical Review

摘要

The demand of configurable and compact RF integrated circuit is ever increasing since the inception of CMOS technology. The inductor has been an essential component in RF system design blocks such as voltage controlled oscillator, low noise amplifier, matching network, filter, power divider, power supply noise reduction etc. The gyrator-C based CMOS active inductor is recent research topic because of its tunability, compactness and high quality factor. This paper presents the detailed review of gyrator-C based CMOS active inductor and several techniques to enhance its performance.
