本文描述了一种毫米波接收器架构，该架构使用一个低噪声放大器（LNA）和一个带有基于相位插值器（PI）的可重构本振（LO）生成系统的次谐波混频器。该接收器采用22纳米CMOS工艺制造，有两种工作模式：1x模式工作在15 - 25吉赫兹，3x模式工作在20 - 37吉赫兹。由于多模式操作，接收器的本振路径具有高能效。所提出的接收器在1x模式下实现了40分贝的峰值增益，在3x模式下实现了30分贝的峰值增益，总功耗分别为57毫瓦和94毫瓦。在1x模式下，本振路径在25吉赫兹时功耗为27毫瓦，在3x模式下，本振路径在25吉赫兹时功耗为15毫瓦。该接收器在两种模式下的中频带宽均为2吉赫兹。
The paper describes a mm-wave receiver architecture that uses a low noise amplifier (LNA) and subharmonic mixer with a reconfigurable LO generation system based on a phase interpolator (PI). The receiver is fabricated in 22nm CMOS and operates in two modes: lx mode from 15-25 GHz and 3x mode from 20-37 GHz. The LO path of the receiver is power-efficient due to the multi-mode operation. The proposed receiver achieves a peak gain of 40 dB in lx mode and 30 dB in 3x mode, with a total power consumption of S7 mW and 94 mW, respectively. The LO path consumes 27 mW at 25 GHz in lx mode and 15 mW at 25 GHz in 3x mode. The receiver has an IF bandwidth of 2 GHz in both modes.
