DIFFERENTIAL CHOPPER COMPARATOR CAPABLE OF REMOVING KICKBACK NOISE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240333271 titled 'DIFFERENTIAL CHOPPER COMPARATOR CAPABLE OF REMOVING KICKBACK NOISE
The differential chopper comparator described in the patent application is a circuit that amplifies the difference between two input signals and compares them to output a digital signal.
- Input terminal circuit receives two input signals and switches them to an intermediate circuit.
- Chopper circuit generates amplified signals by amplifying the difference between the input signals.
- Comparison circuit compares the amplified signals and outputs a digital signal at a logic level.
- Compensation circuit offsets the amplified signals to remove kickback noise induced in the input terminal circuit.
- The technology shortens settling time and operates at high speed.
Potential Applications: - Precision measurement devices - Signal processing systems - Instrumentation and control systems
Problems Solved: - Reduced settling time in comparator circuits - Minimized kickback noise in input terminal circuits
Benefits: - Improved accuracy in signal comparison - Enhanced performance in high-speed applications - Reduced noise interference in measurement systems

Questions about the technology: 1. How does the compensation circuit offset the amplified signals to remove kickback noise? 2. What are the key advantages of using a chopper circuit in signal processing applications?
Frequently Updated Research: Ongoing research on improving the speed and accuracy of differential chopper comparators in various industrial applications.
Original Abstract Submitted
disclosed is a differential chopper comparator, which includes an input terminal circuit that receives a first input signal and a second input signal and selectively switches the first and second input signals to intermediate circuit, at least one chopper circuit that generates a first amplified signal and a second amplified signal by amplifying a difference between the first and second input signals at the intermediate circuit points, a comparison circuit that compares the first amplified signal with the second amplified signal, digitizes the comparison result, and outputs a digital signal at a logic level, and a compensation circuit that offsets the first amplified signal and the second amplified signal and thereby removes kickback noise induced in the input terminal circuit. the differential chopper comparator of the present disclosure may shorten the settling time and may operate at high speed.
