Abstract

A wideband CMOS receiver front-end for radio applications operating between 300 MHz and 900 MHz is presented. In order to obtain channel selection with image-rejection and out-of-band interferers attenuation, both low-noise amplifier (LNA) and mixer incorporate a N-Path signal processing technique. The effectiveness of this N-Path filtering is investigated by comparing distinct combinations of clock phases and respective duty cycle. Using a standard 130 nm CMOS technology and a supply voltage of 1.2 V, it was possible to obtain a voltage gain greater than 28 dB, a noise figure (NF) lower than 6.05 dB and IIP3 > -1.54 dBm.
