A low power low noise 0.7V mixer first RF frontend for an IEEE 802.15.6 narrowband receiver is presented which uses passive coupling based frequency translated mutual noise cancellation. 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 paper tackles the noise figure and power consumption problems of sub 1V mixers. The FOM is 10dB higher and power consumption is 194μW which is 0.5X lower than the state of the art. The LO power used is -14dBm.
