ANALOG DIGITAL CONVERTER AND METHOD FOR ANALOG TO DIGITAL CONVERTING IN THE ANALOG DIGITAL CONVERTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18057969 titled 'ANALOG DIGITAL CONVERTER AND METHOD FOR ANALOG TO DIGITAL CONVERTING IN THE ANALOG DIGITAL CONVERTER
Simplified Explanation
The patent application describes an analog-to-digital converter (ADC) that includes a comparator, control logic, and a reference voltage adjustment circuit. The ADC converts analog signals into digital signals.
- The comparator receives outputs from multiple capacitors and compares them to determine the digital value of the input signal.
- The control logic generates control signals based on the comparator's output, which are used to adjust the reference voltage provided to the comparator.
- The reference voltage adjustment circuit consists of a pull-up circuit and a pull-down circuit.
- The pull-up circuit applies a first reference voltage to the first unit capacitors, while the pull-down circuit applies a second reference voltage to the second unit capacitors.
Potential applications of this technology:
- Data acquisition systems: The ADC can be used in various data acquisition systems, such as sensors, measurement devices, and industrial control systems.
- Communication systems: The ADC can be utilized in communication systems to convert analog signals into digital format for processing and transmission.
- Audio and video processing: The ADC can be employed in audio and video processing applications, such as audio recording, video surveillance, and multimedia devices.
Problems solved by this technology:
- Improved accuracy: The reference voltage adjustment circuit helps in maintaining accurate conversion of analog signals into digital signals.
- Noise reduction: The comparator and control logic ensure that the reference voltage is adjusted properly, reducing noise and improving the quality of the digital output.
- Simplified design: The use of unit capacitors and the reference voltage adjustment circuit simplifies the overall design of the ADC.
Benefits of this technology:
- Higher resolution: The ADC provides higher resolution in converting analog signals into digital signals, resulting in more precise measurements and data.
- Reduced power consumption: The simplified design and efficient reference voltage adjustment circuit contribute to lower power consumption of the ADC.
- Cost-effective: The use of unit capacitors and the simplified design make the ADC more cost-effective to manufacture and implement.
