AUDIO AMPLIFIER AND METHOD OF OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240267008 titled 'AUDIO AMPLIFIER AND METHOD OF OPERATING THE SAME
The abstract describes an audio amplifier system that includes a loop filter, a pulse-width modulation (PWM) signal generator, a driver, a feedback circuit, and a common mode compensation circuit.
- The loop filter receives a differential input signal pair.
- The PWM signal generator generates PWM signals based on the input signals received from the loop filter.
- The driver generates an output signal pair based on the PWM signals.
- The feedback circuit feeds back the output signal pair to the loop filter.
- The common mode compensation circuit compensates for fluctuations in the common mode voltage of the fed-back output signal pair.
Potential Applications: - Audio amplifiers in various electronic devices - Signal processing systems - Communication systems
Problems Solved: - Maintaining signal integrity in audio amplification - Compensating for common mode voltage fluctuations
Benefits: - Improved audio signal quality - Enhanced performance of audio amplifiers - Increased efficiency in signal processing
Commercial Applications: Title: "Advanced Audio Amplifier Systems for High-Fidelity Sound Systems" This technology can be used in high-end audio equipment, professional sound systems, and automotive audio systems, enhancing the overall audio experience for users.
Questions about the technology: 1. How does the common mode compensation circuit improve the performance of the audio amplifier system? - The common mode compensation circuit ensures that any fluctuations in the common mode voltage do not affect the output signal quality, resulting in a more stable and accurate audio amplification process.
2. What are the key advantages of using a loop filter in the audio amplifier system? - The loop filter helps in processing the input signals effectively, leading to better control over the generation of PWM signals and ultimately improving the overall performance of the amplifier.
