==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 17949149 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 SAR ADCs with variable resolution, where the quantization size of the LSB depends on the amplitude of the analog input signal.

* SAR ADCs are configured to convert analog input signals to digital output signals.
* The quantization size of the LSB is variable and depends on the amplitude of the analog input signal.
* This allows for a higher maximum sampling rate or lower power dissipation in the SAR ADC.

== Potential Applications ==
The technology can be applied in various fields such as telecommunications, medical devices, industrial automation, and consumer electronics.

== Problems Solved ==
1. Higher maximum sampling rate
2. Lower power dissipation

== Benefits ==
1. Improved efficiency in converting analog signals to digital
2. Enhanced performance in various applications
3. Potential cost savings in power consumption

== Potential Commercial Applications ==
Optimizing SAR ADCs with variable resolution for specific industries like telecommunications, medical devices, and consumer electronics.

== Possible Prior Art ==
Prior art may include existing techniques for SAR ADCs with fixed resolution or other methods for improving ADC performance.

== Unanswered Questions ==

=== How does the variable resolution of the SAR ADC impact its overall accuracy? ===
The abstract does not provide specific details on how the variable resolution affects the accuracy of the ADC.

=== Are there any limitations to implementing variable resolution in SAR ADCs? ===
The abstract does not mention any potential challenges or limitations that may arise when implementing variable resolution in SAR ADCs.


==Original Abstract Submitted==

Techniques and apparatus for successive approximation register (SAR) analog-to-digital converters (ADCs) with variable resolution. One example SAR ADC is generally configured to convert an analog input signal to a digital output signal, wherein a quantization size of a least significant bit (LSB) associated with the digital output signal is configured to depend on an amplitude of the analog input signal. By utilizing the techniques and apparatus described herein, a SAR ADC may be capable of a higher maximum sampling rate or a lower power dissipation.
