In this chapter, 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 (FOM) is 10 dB higher and the power consumption is 194 μW which is 0.5X lower than the state of the art. The local oscillator (LO) power used is − 14 dBm.
