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