A regenerative frequency divider device including a plurality of multipliers, each of which has a first input port, a second input port and an output port; a first combiner coupled to the plurality of multipliers so as to receive an output signal from at least two of the multipliers; and a second combiner coupled to the plurality of multipliers so as to receive an output signal from at least two of multipliers. Further, a first output signal generated by the first combiner is coupled to the second input port of at least two of the multipliers; and a second output signal generated by the second combiner is coupled to the second input port of at least two of the multipliers such that a complex signal is fed back to the multipliers performing the down conversion process. The present invention divider CRD can achieve superior output noise floor of -180 dBc/Hz at multi-GHz frequencies.
