Abstract
A receiver () includes a transconductance mixer (), a polyphase filter (), and a transimpedance amplifier (). The transconductance mixer () mixes a radio frequency (RF) voltage signal into a current signal having a plurality of phases using a local oscillator signal. The polyphase filter () filters the current signal to provide a filtered current signal. The transimpedance amplifier () converts the filtered current signal into an output voltage signal.
