Embedded instrumentation architecture
| DWPI Title: Integrated circuit, has process signal which is directed to each of first and second output pin and thus a first and second sample of process signal is received by first and second analog to digital (A/D) converters |
| Abstract: The various technologies presented herein relate to generating copies of an incoming signal, wherein each copy of the signal can undergo different processing to facilitate control of bandwidth demands during communication of one or more signals relating to the incoming signal. A signal sharing component can be utilized to share copies of the incoming signal between a plurality of circuits/components which can include a first A/D converter, a second A/D converter, and a comparator component. The first A/D converter can operate at a low sampling rate and accordingly generates, and continuously transmits, a signal having a low bandwidth requirement. The second A/D converter can operate at a high sampling rate and hence generates a signal having a high bandwidth requirement. Transmission of a signal from the second A/D converter can be controlled by a signaling event (e.g., a signal pulse) being determined to have occurred by the comparator component. |
| Use: Integrated circuit for use in sensors such as thermocouple, pressure sensor, accelerometer, composition determining component, etc. |
| Advantage: The transmission of a digitized signal formed from the second copy of the incoming signal is controlled based on an importance of the digitized signal. The output signals are discarded as at the source, and thus to prevent unwanted bandwidth burden occurring. |
| Novelty: The integrated circuit has a signal sharing component which receives a process signal on the input pin. The process signal is directed to each of first output pin and second output pin, such that a first sample (136A) and second sample (136B) of the process signal is received by the first and second analog to digital (A/D) converters. The first and second A/D converters processes the first and second samples of the process signal at a first and second sampling rate to form a first and second converted signal respectively. The first sampling rate is lower than the second sampling rate. |
