Abstract
A digital pressure sensor system is disclosed wherein a pressure differential causes the resistance of two equal, diffused piezoresistors to change by equal but opposite amounts. Temperature compensation is achieved by using the temperature dependency of the piezoresistors in combination with a temperature reference resistor to establish a plurality of time durations of a distinct voltage level. The ratio of these time durations forms a temperature compensation factor which may be used to compensate the pressure reading.
