Pressure monitoring circuits and methods

摘要

A pressure monitoring device comprises an analog-to-digital converter (ADC) to receive an analog signal and to convert the analog signal to a digital signal. The pressure monitoring device is configured to apply in a first state a first set of calibration coefficients to the digital signal, the first set of calibration coefficients being associated with a first pressure range. The pressure monitoring device is further configured to apply in a second state a second set of calibration values to the digital signal, the second set of calibration coefficients being associated with a second pressure range different than the first pressure range.

1. A pressure monitoring device comprising:
an analog-to-digital converter (ADC) to receive an analog signal and to convert the analog signal to a digital signal; wherein the device is configured to apply in a first state a first set of calibration coefficients to the digital signal, the first set of calibration coefficients associated with a first pressure range and to apply in a second state a second set of calibration coefficients to the digital signal, the second set of calibration coefficients associated with a second pressure range different than the first pressure range, and wherein endpoints bounding the first pressure range are separated by a first difference that is greater than a second difference separating endpoints bounding the second pressure range.
