Low-power integrated radio frequency power detector

A method for generating a voltage at a circuit comprising:

• generating, at a first rectifier core of a rectifier of the circuit, a first current reference associated with a difference between differential radio frequency (RF) input terminals of the rectifier, wherein the rectifier comprises differential RF input terminals;
• generating, at a second rectifier core of the rectifier, a second current reference associated with a common mode of the differential RF input terminals;
• generating, at a third rectifier core of the rectifier, a first reference voltage based at least in part on a bias voltage of the differential RF input terminals;
• generating, at a fourth rectifier core of the rectifier, a rectifier output current based at least in part on the first current reference and the second current reference;
• and
• generating, at a first amplifier of the circuit, the voltage, wherein the voltage is logarithmically related to the rectifier output current and is based at least in part on the rectifier output current and the first reference voltage.
