ABSTRACT:
An integrated detector circuit (20) includes first and second gain stages (GS1, GS2). The first gain stage has an input (82) that monitors a high frequency signal (VRFDET) for routing a first detection current (IS1) to a node (60). The second gain stage includes a first current source (PF1) that supplies a bias current (IMAX1) 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 (IS2), 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.
