摘要

本文提出了一个模拟基带部分，实现了40 nm数字低功耗(LP) CMOS 60 GHz发射机的波束形成功能。在使用1.1 V电源的电路中，在整个频带上获得了大于240 mVpeak的输入1dB压缩点。获得了22.5度的目标相移分辨率。全自动，数字辅助直流偏移补偿也存在于芯片上。电流消耗为70ma。

Analog baseband beamformer for use in a phased-array 60 GHz transmitter

This paper presents an analog baseband section that implements the beamforming functionality of a 40 nm digital low-power (LP) CMOS 60 GHz transmitter. An input 1dB compression point larger than 240 mVpeak over the whole band is obtained, in a circuit operating with a 1.1 V supply. The targeted phase shift resolution of 22.5 degrees is obtained. Fully automatic, digitally assisted DC offset compensation is also present on-chip. The current consumption is 70 mA.
