Low pass filter semiconductor structures for use in transducers for measuring low dynamic pressures in the presence of high static pressures |
摘要 |
A semiconductor filter is provided to operate in conjunction with a differential pressure transducer. In one embodiment, a method comprises receiving, at a filter having a plurality of apertures, a pressure, wherein the pressure includes a static pressure component and a dynamic pressure component; filtering, by the plurality of apertures, at least a portion of the dynamic pressure component of the pressure, wherein a diameter of each of the plurality of apertures is such that the plurality of apertures filters at least the portion of the dynamic pressure component of the pressure; outputting, from the filter, a filtered pressure; and wherein the filtered pressure is used to determine the dynamic pressure component of the pressure. |

1. A method, comprising:
receiving, at a filter having a plurality of apertures, a pressure, wherein the pressure includes a static pressure component and a dynamic pressure component; filtering, by the plurality of apertures, at least a portion of the dynamic pressure component of the pressure, wherein a diameter of each of the plurality of apertures is such that the plurality of apertures filters at least the portion of the dynamic pressure component of the pressure; outputting, from the filter, a filtered pressure; and wherein the filtered pressure is used to determine the dynamic pressure component of the pressure. |
