Abstract
In some embodiments, a compensated power detector can include a power detector that includes a first detection cell having a bias input and an output, and a second detection cell having a signal input, a bias input and an output. The power detector can further include an error amplifier having a first input coupled to the output of the first detection cell, and a second input for receiving a reference voltage. The error amplifier can be configured to provide an output voltage to each of the bias inputs of the first and second detection cells, such that an output of the second detection cell is representative of power of a radio-frequency signal received at the signal input with an adjustment for one or more non-signal effects as measured by the first detection cell and the error amplifier.
