Abstract
A local oscillation generator includes a multi-phase circuit and a multiplexer. The multi-phase oscillator provides a plurality of multi-phase oscillation signals of a same frequency and different phases. The multiplexer conducts one of the multi-phase oscillation signals to an output end in different time slots to provide an output oscillation signal. The frequency of the multi-phase oscillation signals is the same as a fundamental frequency, and the frequency of the output oscillation signal is different from the fundamental frequency. Thus, the local oscillation generator provides a local oscillation signal according to the output oscillation signal such that the fundamental frequency is different from the frequency of the local oscillation signal.
