DYNAMIC RANGE BOOST FOR AMPLIFIERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240223206 titled 'DYNAMIC RANGE BOOST FOR AMPLIFIERS

The abstract describes an example of an amplifier with associated control blocks that control analog and digital gains to maintain a ripple voltage at the input/virtual terminals of an internal integrator below an upper limit. The amplifier includes digital and analog processing blocks, a boost controller, and a digital controller.

• The digital processing block receives a digital audio signal and includes a digital gain component.
• The analog processing block includes an analog gain component and an output stage with a supply voltage terminal.
• The boost controller receives the digital audio signal and outputs a boost voltage.
• The digital controller receives the digital audio signal, the boost voltage output, and controls the digital and analog gain components based on its inputs.

Potential Applications: - Audio amplification systems - Signal processing applications - Voltage regulation systems

Problems Solved: - Maintaining ripple voltage within specified limits - Controlling analog and digital gains effectively

Benefits: - Improved audio signal quality - Enhanced voltage regulation - Efficient control of amplifier gains

Commercial Applications: Title: "Advanced Amplifier Control System for Audio Applications" This technology can be used in high-end audio systems, professional sound equipment, and industrial automation processes where precise control of amplifier gains is crucial for optimal performance.

Questions about the technology: 1. How does the digital controller adjust the analog and digital gains based on the inputs it receives? - The digital controller uses the information from the boost controller and the measurement value of the boost voltage to determine the appropriate adjustments to the gains. 2. What are the key advantages of using both digital and analog processing blocks in this amplifier system? - The combination of digital and analog processing allows for efficient control of gains while maintaining high-quality audio output.
