Abstract:
An electronic communication device includes an antenna configured to receive a radio frequency (RF) signal and generate a differential current signal. A mixer circuit is configured to downconvert a differential voltage to generate an output voltage. The differential voltage is generated from the differential current signal, and the output voltage is used for detecting the RF signal.
