Title: Innovations of Yun-Hwan Jung
Introduction
Yun-Hwan Jung is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of digital signal processing, particularly in the development of advanced digital to analog converters. With a total of three patents to his name, Jung's work showcases his expertise and innovative spirit.
Latest Patents
One of his latest patents is a "Direct Digital Frequency Synthesizer Using Hybrid Digital to Analog Converter and Synthesizing Method Thereof." This invention involves a direct digital frequency synthesizer that utilizes a hybrid digital to analog converter. The hybrid DAC matches the output data of a phase accumulator to a sine wave amplitude, incorporating both non-linear and linear DACs. The non-linear DAC generates a direct base point current based on certain bits of the output data, while the linear DAC produces a gradient current using other bits. These currents are then summed to create the final analog output.
Another significant patent is the "Return to Zero Digital to Analog Converter and Converting Method Thereof." This invention pertains to a digital to analog converter that enhances wideband characteristics by enabling a return-to-zero output without the need for a separate clock and controller. The converter achieves this by configuring a switch to generate a zero point signal and employing a differential pipeline to provide a differential signal based on input digital data. This innovative approach allows for high dynamic performance and wideband characteristics.
