摘要

提出了一种增益和功耗数字可控的可重构低噪声放大器。这种架构只允许在需要时增加功耗，也就是说，在极端通信信道条件下提高LNA的射频性能和/或抵消工艺、电压和温度变化的影响。当可接受放松操作时，所建议的设计可显著节省电力。LNA采用130 nm 1.2 V CMOS技术实现，适用于2.4 GHz IEEE-802.15.4应用。模拟的LNA性能(考虑到过程变化下的最坏情况)与最近发表的作品相当。

Energy-Aware Low-Power CMOS LNA with Process-Variations Management

A reconfigurable low-noise amplifier (LNA) with digitally controllable gain and power consumption is presented. This architecture allows increasing power consumption only when required, that is, to improve LNA’s radiofrequency performance at extreme communication-channel conditions and/or to counteract the effect of process, voltage, and temperature variations. The proposed design leads to significant power saving when a relaxed operation is acceptable. The LNA is implemented in a 130 nm 1.2 V CMOS technology for a 2.4 GHz IEEE-802.15.4 application. Simulated LNA performance (taking into account the worst cases under process variations) is comparable to recently published works.
