Abstract
This article presents a low-power passive mixer-
first receiver (MFRX) with an N-path harmonic-rejection (HR)
transformer-mixer for narrowband Internet-of-Everything (IoE)
applications. Composed of only switches and capacitors, the
N-path HR transformer-mixer integrates the behavior of a
transformer and harmonic recombination into the passive mixer
itself, providing voltage gain, HR, and high- Q filtering before
any active components. A prototype RX in 22-nm fully-depleted
silicon-on-insulator (FD
