摘要

本文提出了一种工作频率为138ghz的40纳米CMOS宽带差分放大器。它由五个差分共源级和交叉耦合电容器组成。实现了138ghz时18db的小信号增益和27ghz的3db带宽。它从0.94 v电压电源消耗75兆瓦。带平衡垫的模具面积为945 × 842 μm2，不含输入/输出匹配网络的芯尺寸为201 × 284 μm2。小的核心区通过使用精致的“鱼骨”布局技术来实现。

Compact 138-GHz amplifier with 18-dB peak gain and 27-GHz 3-dB bandwidth

This paper presents a wideband differential amplifier operating at 138 GHz in 40-nm CMOS. It is composed of five differential common source stages with cross-coupled capacitors. A small-signal gain of 18 dB at 138 GHz and a 3-dB bandwidth of 27 GHz are achieved. It consumes 75 mW from a 0.94-V voltage supply. The die area with balun and pads is 945 × 842 μm2 and the core size not including input/output matching networks is 201 × 284 μm2. The small core area is realized by using a refined "fishbone" layout technique.
