Abstract

A low-power low-noise 0.7-V mixer-first RF frontend for an IEEE 802.15.6 narrowband receiver is presented, which uses frequency translated mutual noise cancellation based on passive coupling. Unlike traditional noise-cancelling techniques, we perform symmetrical noise cancellation of a fully differential structure where each path cancels the noise of the other at IF. This prototype design realized in TSMC's 65-nm CMOS tackles the noise figure and power consumption problems of sub-1-V mixers. The figure of merit is 10 dB higher and the power consumption is 194 μW, which is 0.5 × lower than the state-of-the-art. The local oscillator power used is-14 dBm.
