ANALOG-TO-DIGITAL CONVERTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240259030 titled 'ANALOG-TO-DIGITAL CONVERTER
The abstract describes an analog-to-digital converter with various components such as chopping switches, integrators, quantizers, and feedback switches. These components work together to convert analog signals into digital signals efficiently.
- The analog-to-digital converter includes an input-signal chopping switch, an integrator, an output chopping switch, a quantizer, and a feedback switch.
- The integrator, which consists of an operational amplifier, an integral capacitor, and an integral-capacitor-chopping input switch, follows the input-signal chopping switch.
- The output chopping switch is positioned after the operational amplifier in the integrator.
- The quantizer is located after the output chopping switch.
- A feedback chopping switch is present in the feedback path from the quantizer's output to the integrator's input.
- All chopping switches operate at the same frequency, ensuring consistency in the conversion process.
Potential Applications: - This technology can be used in various electronic devices that require precise analog-to-digital conversion, such as sensors, data acquisition systems, and communication devices.
Problems Solved: - The analog-to-digital converter addresses the need for accurate and efficient conversion of analog signals into digital format.
Benefits: - Improved accuracy and reliability in converting analog signals to digital format. - Consistent performance due to the synchronized operation of chopping switches. - Enhanced signal processing capabilities in electronic devices.
Commercial Applications: - This technology can be applied in industries such as telecommunications, automotive, healthcare, and consumer electronics for signal processing and data acquisition purposes.
Questions about the technology: 1. How does the synchronized operation of chopping switches improve the performance of the analog-to-digital converter? 2. What are the key advantages of using an integrator in the conversion process?
Original Abstract Submitted
an analog-to-digital converter includes an input-signal chopping switch, an integrator, an output chopping switch, a quantizer, and a feedback switch. the integrator is located after the input-signal chopping switch. the integrator includes an operational amplifier, an integral capacitor, and an integral-capacitor-chopping input switch being at on an input side of the integral capacitor. the output chopping switch is on an output side of the operational amplifier. the quantizer is located after the output chopping switch. the feedback chopping switch is in a feedback path from an output of the quantizer to an input of the first integrator. the input-signal chopping switch, the integral-capacitor-chopping input switch, the output chopping switch, and the feedback chopping switch execute chopping at an identical frequency. the output chopping switch sets a polarity of an input value of the quantizer to be identical before and after the chopping.
