Abstract
One embodiment is a reconfigurable mixer topology for selectively implementing one of a harmonic rejection mixer (HRM) and a subharmonic mixer (SHM), the reconfigurable mixer topology comprising a mixer core comprising a plurality of differential mixers each having a first clock input and a second clock input; a clock generator for generating a plurality of clock signals each having a different phase; and a clock distributor for distributing the plurality of clock signals to the first and second clock inputs of the differential mixers in accordance with a designated operation of the reconfigurable mixer as an HRM or an SHM.
