Abstract
Various approaches of receiving signals in integrated circuitry include implementing a voltage-mode passive mixer for down-converting the frequency of the received signals, a baseband output buffer, and a transconductance amplifier coupled between the voltage-mode passive mixer and baseband output buffer for presenting a high-impedance load to the voltage-mode passive mixer and shielding the baseband output buffer from a high-frequency feedthrough.
