Abstract: A pressure sensing system and method includes a pressure sensor configured to include a pressure sensing diaphragm and a pressure port. A memory circuit incorporated can be incorporated into the pressure port. A high order polynomial component can also be provided. One or more excitation signals are then applicable to the pressure sensor such that a voltage output thereof is measured and recorded at a plurality of predefined temperatures and pressures in order to generate pressure sensor output data. Such output data is then automatically input to the high order polynomial component in order to generate a set of correction coefficients usable for improving the accuracy of the pressure sensor. The pressure sensing diaphragm is preferably based on an Advanced Thick Film (ATF) configuration.

Abstract: An output sensor apparatus, system, and method are disclosed, including a circuit comprising a plurality of bridge resistors and one or more connecting resistors coupled to the plurality of bridge resistors. Additionally, a programmable amplifier can be coupled to the connecting resistor, wherein the circuit produces an output signal that changes in a manner similar to that of an output of a Wheatstone bridge circuit sensor. Thus, a circuit can be provided, which can be effortlessly added to a readily available programmable integrated circuit (IC) chip.
