FREQUENCY CONVERTER BY USING MULTIPLEX PHASE MIXER, ESPECIALLY SAVING COST AND REDUCING POWER CONSUMPTION RELATIVELY

摘要

PURPOSE: A frequency converter by using a multiplex phase mixer is provided to generate the output signal having a frequency near to the direct current by drastically adjusting the frequency of the received wireless communication signal downward. CONSTITUTION: A frequency converter by using a multiplex phase mixer includes an oscillator and a mixer. The oscillator is provided with the i-th clock signal, the i-th oscillation signal and the i-th inverse oscillation signal. The mixer is provided with a loading unit, an input unit and a driving unit. The loading unit is provided with a first load device formed between both the predetermined power voltage and the positive output terminal and a second load device formed between the power voltage and the negative output terminal. The loading unit generates the modulation output signal by supplying the voltage difference of the signal supplied from the positive output terminal and the negative output terminal. And, the driving unit controls the amount of current flowing the first and the second load devices in response to the first to nth clock signals and generates the modulation output signal finally.
