Abstract: Pressure sensor circuit (12) develops an input sensor signal (V01) varying linearly as a function of sensed pressure (P) over a range (P.sub.1) of pressure. An error reduction circuit (14-21, R10-R14) having operational amplifiers (16, 19) and a semiconductor device (21) receives the input sensor signal and provides an output signal (V.sub.OUT). The output signal varies at a first high constant rate during a first portion (P.sub.2) of the pressure range and at a lower constant rate during a second portion (P.sub.3) of the pressure range. A break point (BP) between the first and second pressure range portions occurs when the input sensor signal magnitude exceeds a voltage level (V.sub.T) magnitude. The rate of change of the output signal during the first pressure range portion exceeds the rate of change of the input sensor signal during this same pressure range and thus the percentage of error of the output signal is less during the first pressure range portion than the percentage of error of the input sensor signal. The break point and rates of change of the output signal are substantially temperature independent and each can be independently adjusted.

Abstract: A media-isolated differential pressure sensor apparatus and corresponding method combines a first signal (207, 209) provided by a first pressure sensor (101), indicative of a difference between a first pressure and second pressure applied across the first pressure sensor, and a second signal (213, 215) provided by a second pressure sensor, indicative of a difference between the second pressure and a third pressure applied across the second pressure sensor (103) to form a differential pressure sensor. Responsive to a pressure span the first signal (207, 209) responds with a slope response different than a slope response of the second signal (213, 215). A slope adjustment circuit (217) enables an adjustment of the slope response of the first signal (207, 209) to correspond to the slope response of the second signal (213, 215), and provides a slope adjusted first signal (221) dependent on the adjusted slope response. A difference circuit (225) provides an output signal (227) dependent on a difference between the slope adjusted first signal (221) and the second signal (223), where the output signal (227) is indicative of a pressure differential sensed between the first pressure sensor (101) and the second pressure sensor (103).

Abstract: A polynomial calculator device is applied to calibrate a sensing device. Preferably the sensing device (100) includes a sensing element (102) with an output coupled to a signal conditioning circuit (104). The signal conditioning circuit (104) is adapted to be highly computationally efficient and operable for compensating for temperature and part-to-part variation on the sensing element output for providing a useable sensor output signal. A calibration method relies on a unique polynomial calculator (118) that is implemented as part of the signal conditioning circuit (104). The sensor is preferably manufactured and packaged prior to calibration so as to avoid any post-calibration processing error. The packaged sensor is calibrated and a number of calibration values are retained in a memory (114) and accessed by the calibration method during sensing element signal processing.
