Abstract
A compensation device that can include a bias-able device, a bias circuit that provides the bias-able device with a bias current, a signal conditioner selectively coupled to the bias-able device, and an emulator. The signal conditioner and emulator can divert current from the bias-able device in an operational and calibration mode, respectively. In calibration mode, the emulator generates a compensation current that is combined with a sense current so that the sense current equals the bias current.
