Abstract :
A low-voltage low-power high-efficiency squarer circuit used as energy collector for 3.1-5 GHz non-coherent UWB applications. The squarer circuit is based on flipped voltage follower circuit, whose bandwidth is extended higher than 5 GHz by choosing device length and bias current properly. The proposed squarer circuit is implemented in 65 nm CMOS process and the transistor level circuit simulation shows that it consumes 1.2 mA current from 0.6 V power supply and that the equivalent conversion gain is 6.3 dB.
