Abstract
A measurement system includes a detector to generate a measurement signal responsive to an input signal, and a nulling circuit coupled to the detector to generate a control signal responsive to the difference between the measurement signal and a set-point signal. The nulling circuit may include a bandwidth compensation stage to maintain the overall control loop bandwidth at a substantially constant value.
