ULTRA-LOW-POWER FRONT END FOR BEYOND-THE-RAILS VOLTAGE SENSING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240053387 titled 'ULTRA-LOW-POWER FRONT END FOR BEYOND-THE-RAILS VOLTAGE SENSING
Simplified Explanation
- A system with a passive floating attenuator receives an analog physical quantity and attenuates it to a floating attenuated signal with different voltage nodes. - An anti-aliasing filter filters the floating attenuated signal to generate a filtered attenuated signal. - A switched-capacitor sampling circuit with multiple switches samples the filtered attenuated signal.
Potential Applications
- Signal processing in communication systems - Data acquisition systems - Sensor networks
Problems Solved
- Preventing aliasing in sampled signals - Improving signal quality and accuracy - Minimizing noise and interference
Benefits
- Enhanced signal processing capabilities - Improved data accuracy - Reduced noise and distortion levels
Original Abstract Submitted
a system may include a passive floating attenuator configured to receive an analog physical quantity and attenuate the analog physical quantity to a floating attenuated signal defined by voltage nodes other than the voltage nodes of the analog physical quantity, an anti-aliasing filter configured to filter the floating attenuated signal to generate a filtered attenuated signal, and a switched-capacitor sampling circuit comprising a plurality of switches configured to sample the filtered attenuated signal.
