Effect of Dummy Fills on Characteristics of Passive Devices in CMOS Millimeter-Wave Circuits

摘要：

This paper discusses issues of dummy II in high frequency CMOS circuits.Dummy II is a small oaring metal to suppress the metal thickness variation.In high trequency, eddy current induced in the dummy IIs affect the electrical performance of passive devices.We introduce the effect on a transmission-line and a spiral inductor.We discuss which dummy IIs have signicant etfect on the performance and show a design strategy of on-chip spiral inductor with dummy IIs.
