Title: Neng-Haung Sheng: Innovator in Digital-to-Analog Conversion Technology

Introduction

Neng-Haung Sheng is a prominent inventor based in Thousand Oaks, California. He has made significant contributions to the field of digital-to-analog conversion technology, holding a total of five patents. His innovative work has advanced the capabilities of digital signal processing.

Latest Patents

One of Sheng's latest patents is a current-steering digital-to-analog converter with dual current switch modules. This invention includes dual current switch modules that receive digital input bits representative of the desired analog output. Each module is controlled by one of the digital input bits, with differential signals representing each bit. The design separates the positive and negative inputs to drive two separate current switches, which helps to reduce switching transition noise. The output currents from these switches are summed in phase, effectively canceling out out-of-phase switching noises.

Another notable patent is a digital-to-analog signal converting apparatus and method that extends the usable spectrum over the Nyquist frequency. This invention utilizes a digital-circuit return-to-zero device and a method for digital-to-analog conversion. It employs an internal multiplexer that selects digital input data and an expansion code, allowing the analog spectrum of the digital-to-analog converter to extend beyond conventional limits. This approach features low complexity and high portability compared to existing solutions.
