Pressure sensor with trim resistors

A pressure sensor comprising:

• a Wheatstone bridge circuit including a first resistor, a second resistor, a third resistor, and a fourth resistor having matching output characteristics;
• a first trim resistor electrically coupled to the Wheatstone bridge circuit, wherein the first trim resistor has output characteristics matching the output characteristics of the first resistor, the second resistor, the third resistor, and the fourth resistor of the Wheatstone bridge circuit;
• and
• a second trim resistor electrically coupled to the Wheatstone bridge circuit, wherein the second trim resistor has output characteristics that are mismatched to the output characteristics of the first resistor, the second resistor, the third resistor, and the fourth resistor of the Wheatstone bridge circuit.

A pressure sensor comprising:

• a first sensor portion having a pressure die with piezoresistors located in a Wheatstone bridge circuit configuration;
• and
• a second sensor portion having a trim die with a first trim resistor positioned on the trim die;
• wherein the pressure die in the first sensor portion is electrically coupled to the trim die in the second sensor portion;
• and
• wherein the first sensor portion and the second portion are positioned apart from one another.
