A pressure transducer that includes at least two sensors having substantially similar or substantially identical error characteristics, wherein each sensor is arranged to be subjected to an applied pressure and the outputs of the sensors are electrically coupled so that errors associated with one sensor are compensated by errors associated with the other sensor. The sensors may be substantially identical silicon sensors formed in close proximity on the same wafer.

[ What is claimed is:] [1.] A pressure transducer comprising:a first sensor; anda second sensor;the first and second sensors having substantially similar error characteristics, each of the first and second sensors being arranged to be subjected to at least one of a first pressure and a second pressure and to provide an output indicative of the pressure exerted thereon, the outputs of the sensors being electrically cross-coupled to each other so that an error in the first sensor is compensated with a substantially similar error in the second sensor.
