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

Description

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 130nm 1.2V CMOS technology for a 2.4GHz IEEE-802.15.4 application. Simulated LNAperformance (taking into account theworst cases under process variations) is comparable to recently published works
