SUCCESSIVE APPROXIMATION REGISTER (SAR) ANALOG-TO-DIGITAL CONVERTER (ADC) WITH INPUT-DEPENDENT LEAST SIGNIFICANT BIT (LSB) SIZE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240097698 titled 'SUCCESSIVE APPROXIMATION REGISTER (SAR) ANALOG-TO-DIGITAL CONVERTER (ADC) WITH INPUT-DEPENDENT LEAST SIGNIFICANT BIT (LSB) SIZE
Simplified Explanation
The abstract describes techniques and apparatus for successive approximation register (SAR) analog-to-digital converters (ADCs) with variable resolution. One example SAR ADC is configured to convert an analog input signal to a digital output signal, where the quantization size of the least significant bit (LSB) associated with the digital output signal depends on the amplitude of the analog input signal. By utilizing these techniques, a SAR ADC may achieve a higher maximum sampling rate or lower power dissipation.
- SAR ADCs have variable resolution based on the amplitude of the analog input signal.
- The quantization size of the least significant bit (LSB) changes dynamically.
- This allows for higher maximum sampling rates or lower power dissipation.
Potential Applications
The technology can be applied in:
- High-speed data acquisition systems
- Wireless communication systems
- Sensor interfaces
Problems Solved
- Achieving higher maximum sampling rates
- Reducing power dissipation in ADCs
Benefits

Possible Prior Art
One possible prior art is the use of fixed-resolution SAR ADCs in various electronic devices and systems.
Unanswered Questions
How does the variable resolution of the SAR ADC impact the overall accuracy of the conversion process?
The variable resolution of the SAR ADC may affect the accuracy of the conversion process, especially at lower amplitudes of the analog input signal. Further research and testing are needed to determine the trade-offs between resolution and accuracy.
What are the potential challenges in implementing SAR ADCs with variable resolution in real-world applications?
Integrating SAR ADCs with variable resolution into existing systems may pose challenges in terms of compatibility, calibration, and signal processing. Research and development efforts are required to address these challenges effectively.
