METHODS AND APPARATUS TO CAPTURE SWITCH CHARGE INJECTIONS AND COMPARATOR KICKBACK EFFECTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18129604 titled 'METHODS AND APPARATUS TO CAPTURE SWITCH CHARGE INJECTIONS AND COMPARATOR KICKBACK EFFECTS
The abstract of the patent application describes an example apparatus with controller circuitry that controls a capacitive digital to analog converter (C-DAC) circuitry by configuring switches into different configurations to perform an Auto Zero (AZ) phase and make AZ decisions.
- Controller circuitry provides switch signals to C-DAC circuitry, which includes switches.
- Switches are configured into a third configuration to begin an Auto Zero (AZ) phase with a third switch in a closed state.
- Switches are then configured into a fourth configuration to repeat the transition of the third switch to the open state corresponding to a first configuration.
- The switches are further configured into a fifth configuration to repeat the transition of a first switch and a second switch to the open state corresponding to a second configuration.
- Switches are then configured into a sixth configuration to repeat the transition of the third switch to the closed state corresponding to a second configuration.
- An AZ decision is performed with the switches in the sixth configuration.
Potential Applications: - This technology could be used in precision measurement devices. - It could be applied in automation systems for calibration purposes.
Problems Solved: - Provides a method for Auto Zero (AZ) calibration in electronic devices. - Ensures accurate and reliable analog to digital conversion.
Benefits: - Improves the accuracy of measurement devices. - Enhances the reliability of electronic systems.
Commercial Applications: Title: Precision Measurement Devices Calibration Technology This technology can be utilized in industries such as: - Manufacturing - Aerospace - Healthcare
Questions about the technology: 1. How does this technology improve the accuracy of measurement devices? 2. What are the potential commercial applications of this calibration technology?
