Title: The Innovative Contributions of Daniel L W Chieng
Introduction
Daniel L W Chieng is a prominent inventor based in Austin, TX, known for his significant contributions to the field of digital audio technology. With a total of 17 patents to his name, Chieng has developed innovative systems and methods that enhance audio performance and efficiency.
Latest Patents
Among his latest patents, Chieng has developed systems and methods for over-current protection in all-digital amplifiers. This invention utilizes low-cost current sensing mechanisms to ensure optimal performance. The over-current hard clipping unit processes a digital audio signal, clipping it according to a specified level before modulating it to produce a PWM signal. This modulated signal is then used to drive a speaker, while an over-current sensing unit monitors the output current against a threshold value. The system intelligently adjusts the clip level based on the current output, ensuring safe operation.
Another notable patent involves implementing a sample rate converter that maximizes speed and flexibility through a combination of hardware and software. This system estimates the sample rate of an input data stream and utilizes a phase selection unit to interpolate filter coefficients. The convolution unit then processes these coefficients with the input samples to produce a re-sampled output data stream. This innovative approach allows for the processing of data streams with independently variable sample rates.
