Abstract

A wideband receiver front-end which uses current-mode and noise cancellation techniques is presented. It is shown that the output impedance of the employed transconductance LNA can be very detrimental for the noise performance. The impact of the output impedance is quantified and considered in the design of a test circuit. An ESD protected prototype is fabricated in 150nm CMOS. Measurement results show a gain of 37dB, NF of 4dB and IIP3>;-15dBm over a bandwidth of 1GHz-3.5GHz. The front-end consumes only 3.55mA from a 1.8V supply and its active area occupies 0.06mm².
