ABSTRACT:
A receiver includes a feedback low noise amplifier (LNA). The feedback LNA has an LNA gain and includes an LNA input configured to receive a signal from an antenna and an LNA output configured to output an amplified voltage signal. The receiver also includes a resistive element, having a resistance, coupled to the LNA output and configured to convert the amplified voltage signal into a current. The receiver also includes a current commuting mixer coupled to the resistive element and configured to receive the current from the resistive element, where the current output by the resistive element is determined at least in part by the amplified voltage signal and the resistance of the resistive element.
