Abstract
A mixer includes a weighting module configured to receive an input signal and to weight the input signal with a set of weighting factors, in order to generate a set of weighted signals; and a switching module configured to receive the set of weighted signals and at least a portion of 2N periodic control signals, wherein each of the periodic control signals has a period of 2N*Tvco which contains a pulse with a pulse width not greater than Tvco; wherein the pulses of the 2N periodic control signals do not overlap with each other; and whereby the switching module outputs the set of weighted signals cyclically, under the control of the received periodic control signals, to generate an output signal with a frequency shift of m/(2N*Tvco), where Tvco denotes a period of a VCO signal, N and m are integers, 0<m<N, compared with the input signal.
