Title: Miaochen Wu: Innovator in High-Speed Data Conversion Technologies

Introduction

Miaochen Wu is a prominent inventor based in Acton, MA (US), known for his contributions to high-speed digital to analog and analog to digital conversion technologies. With a total of 4 patents to his name, Wu has made significant advancements in the field of data interfaces and signal processing.

Latest Patents

Wu's latest patents include a "Data interface with delay locked loop for high speed digital to analog converters and analog to digital converters." This innovative system features a first circuit that includes a data transmitter circuit transmitting digital data based on a first clock signal. A sync generator outputs a sync signal based on the first clock signal, while a digital to analog converter circuit includes a data receiver circuit that latches the digital data based on a second clock signal. The digital to analog converter core receives an output from the data receiver circuit, and a delay locked loop circuit determines a delay based on the second clock signal and the sync signal, ultimately outputting the first clock signal to the first circuit based on the second clock signal and the delay.

Another notable patent is the "Sigma delta modulator with SAW filter." This device and method are designed for filtering high-frequency intermediate frequency signals. A summing amplifier receives the analog intermediate frequency signal and provides an analog signal to a surface acoustic wave filter (SAW) for conversion to a digital quantity. A quantizer digitizes the signal to produce a digitized intermediate frequency signal, while a digital to analog converter provides feedback from the quantizer output signal to the summing amplifier, forming a sigma delta modulation device. The SAW filter ensures high stop band attenuation of signal images within the intermediate frequency signal, producing a low noise signal with minimal intermodulation products.
