Abstract

Recent work on RF receivers has exploited N-path filters to address two critical issues, namely, blocker tolerance and high RF selectivity [1,2]. However, these designs face three drawbacks: (1) the low-noise amplifier (LNA) incorporates a G_m stage that, even with a virtual ground at its output nodes, must still withstand strong blockers at its input; (2) the low-order filter transfer function does not provide sufficient selectivity in narrow-band applications such as GSM or WCDMA; (3) they consume roughly 60mW around 2GHz.
