Abstract:
Some aspects of the present disclosure provide for a sensor system having a large range between minimum and maximum allowed input quantities. In some embodiments, the sensor system has a nonlinear sensor and a linear sensor. The nonlinear sensor is generates a first nonlinear signal corresponding to a detected physical input quantity. The linear sensor generates a second linear signal corresponding to the detected physical input quantity. A signal processor receives the first nonlinear signal and the second linear signal and generates a composite output signal that corresponds to the detected physical input quantity. The composite output signal is a combination of the first nonlinear signal and the second linear signal that provides for a signal having a high sensitivity to small physical input quantities while avoiding saturation at large physical input quantities.
