An apparatus includes a sensor excited by an input voltage adapted to provide a sensor output first voltage corresponding to a physical input excitation. A transformation circuit device provides the operational voltage to the sensor, detects the sensor output first voltage, nulls an amount of offset voltage in the sensor output first voltage, amplifies the nulled offset sensor output first voltage, and provide a noise filtered and temperature compensated output second voltage. A simulator circuit receives the compensated output second voltage and provides an output third voltage representative of a simulated bridge sensor, being absent of offset voltage, and being independent of temperature dependence and noise in the sensor.
