摘要

下一代射电望远镜将有非常多的天线元件。对于这样的系统，超低噪声环境温度集成CMOS接收器可以解决一些设计挑战，如尺寸、重量、功耗和成本。本文介绍了一种这样的接收机的研制。采用65纳米台积电CMOS技术开发，工作频率在0.7 ~ 1.5GHz之间，1.5GHz时的最低噪声温度为16 K，功率增益为70 dB，功耗为265 mW。

Development of a CMOS receiver for a radio-telescope phased-array feed

Next generation radio telescopes will have a very large number of antenna elements. For such systems, ultra-low-noise ambient-temperature integrated CMOS receivers can address some design challenges, such as size, weight, power consumption, and cost. This paper describes the development of one such receiver. Developed in 65-nm TSMC CMOS, it operates between 0.7 and 1.5 GHz and achieves minimum noise temperatures of 16 K at 1.5GHz and power gain of 70 dB, while consuming 265 mW of power.
