Abstract
The present general inventive concept is directed to provide a saturation prevention method that utilizes transfer function modulation to continuously and precisely condition signals over more than four orders of magnitude from a signal source. To avoid signal conditioning error and large transient behavior due to range switching, continuous conditioning of all ranges without saturation over the entire large input dynamic range is employed. The use of transimpedance amplifiers in an example embodiment induces negligible loading on the signal source such that the integrity of the original signal is fully maintained, enabling precise signal conditioning. The ratio of gain to input impedance with a transimpedance amplifier is orders of magnitude larger than other typical methods of signal conditioning, making these amplifiers optimum for the saturation prevention method. An example embodiment utilizes the saturation prevention method to maintain the expected signal gain and a low impedance load for the signal source to ensure the desired accuracy of the signal conditioning.
