SIGNAL CONVERTER FOR A WIRELESS COMMUNICATION AND A RECEIVING APPARATUS, PARTICULARLY FOR CONVERTING A SINGLE ENDED RADIO FREQUENCY SIGNAL INTO A SINGLE ENDED RADIO FREQUENCY SIGNAL THROUGH LOW NOISE AND LOW POWER

摘要

PURPOSE: A signal converter for a wireless communication and a receiving apparatus are provided to improve noise index and reduce power consumption when converting a radial frequency signal of a single phase into a differential signal.;CONSTITUTION: A differential signal converter(400) receives a radial frequency signal of a single phase format, and converts the received radial frequency signal into a radial frequency signal of the differential format. A frequency down-converter(500) converts the radial frequency signal of differential format into a down frequency. The differential signal converter includes a common gate amplifier and a common source amplifier which consume the same bias current source.;COPYRIGHT KIPO 2010
