在毫米波频率下,大晶体管内部的分布式互连寄生效应会显著降低输出功率和效率。本文提出了一个模型,这种结构,并提出了一种布局技术,以减少源极端子寄生效应。该技术应用于65纳米CMOS技术的60 GHz原型,将输出功率从5 dBm提高到10 dBm,漏极效率从3.7%提高到10.7%。
The distributed interconnect parasitics within large transistors markedly degrade the output power and efficiency at millimeter-wave frequencies. This paper develops a model for such structures and proposes a layout technique to reduce the effect of source terminal parasitics. The technique is applied to a 60-GHz prototype in 65-nm CMOS technology, raising the output power from 5 to 10 dBm and the drain efficiency from 3.7% to 10.7%.
