description An aspect relates to an apparatus including a radio frequency (RF) signal power detector. The RF signal power detector includes a first current source configured to generate a first current based on a power level of a first RF signal; a transimpedance amplifier (TIA) configured to generate a first voltage based on the first current, wherein the TIA is coupled between a first upper voltage rail and a lower voltage rail; and a second current source configured to generate a second current related to the first current, wherein the first and second current sources are coupled in series between a second upper voltage rail and the lower voltage rail.
