Abstract
An integrated detector circuit () includes first and second gain stages (GS, GS). The first gain stage has an input () that monitors a high frequency signal (V) for routing a first detection current (IS) to a node (). The second gain stage includes a first current source (PF) that supplies a bias current (I) indicative of a predefined amplitude of the high frequency signal. An input of the second gain stage monitors the high frequency signal to route a portion of the bias current to the node as a second detection current (IS), which is limited to the bias current when the high frequency signal is greater than the predefined amplitude to compensate for a nonlinearity in a transconductance of the second gain stage.
