Exemplary embodiments are disclosed of methods and systems of power detection in RF circuits to provide gain compensation for vehicle systems. In exemplary embodiments, a module (e.g., a front end module (FEM), compensor, compensator, etc.) includes a gain modifier, a power detector, and a controller. The power detector is configured to detect a power output of the gain modifier. The controller is configured to determine a mean of n samples taken by the power detector. The controller is also configured to determine a boundary to mean ratio of the n samples. The controller is further configured to adjust a detected value of the power detector based on the mean and the boundary to mean ratio.

Methods and systems of power detection

Exemplary embodiments are disclosed of current control circuits and methods of modulating supply current from a first device (e.g., a telematics control unit (TCU), etc.) to one or more second devices (e.g., one or more compensators, etc.). In an exemplary embodiment, a method includes modulating a supply current from a first device to a second device into different current values for reporting different information from the second device to the first device. An exemplary embodiment of a current control circuit includes a variable voltage source electrically coupled with a current source and a current sink. The current control circuit is configured to modulate the supply current from a first device to the second device into different current values for reporting different information from the second device to the first device.
