摘要

提出了一种用于车载雷达的40nm CMOS工艺的77GHz功率放大器。在放大器设计中采用对称电流型功率合成器，以扩大带宽，丰富效率，最大限度地提高输出功率。扩音器的小信号增益为16.4dB，带宽为3db，范围为68 ~ 85GHz。该放大器的饱和输出功率(Psat)为17dBm, Psat- 1db带宽在70-100GHz范围内为30GHz，峰值功率增加效率(PAE)为20%。

A 68-85GHz Current-Combining Power Amplifier with 20% PAE and 17dBm Psat in 40-nm CMOS

This paper presents a 77GHz power amplifier (PA) in 40nm CMOS technology for automotive radars. A symmetrical current-mode power combiner is adopted in the PA design to extend bandwidth, enrich efficiency, and maximize output power. The small-signal gain of the PA is 16.4dB with a 3-dB bandwidth from 68 to 85GHz. The proposed PA achieves a saturated output power (Psat) of 17dBm, Psat-1dB bandwidth of 30GHz from 70-100GHz, and peak power-added efficiency (PAE) of 20%.
