Title: Innovations of Marcial K Chua
Introduction
Marcial K Chua is an accomplished inventor based in Thousand Oaks, CA. He has made significant contributions to the field of phase interpolation technology. With a total of 3 patents to his name, Chua continues to push the boundaries of innovation in his area of expertise.
Latest Patents
One of Chua's latest patents is focused on a phase interpolator. This apparatus implements several high-performance phase interpolators. Some embodiments are directed to a full-wave integrating phase interpolation core comprising two pairs of in-phase and quadrature-phase current DACs arranged in a cascode architecture. This design drives an integrating capacitor to produce an interpolation voltage waveform. The current DACs are biased, weighted, and controlled by in-phase and quadrature-phase input clocks. This yields an interpolation waveform that presents a phase value between the phases of the input clocks. Additionally, some embodiments deploying the interpolator core use feedback circuitry and reference voltages. This adjustment optimizes performance and operation within the interpolator's linear region or output compliance range. Both single-core and dual-core implementations, as well as other variations of the interpolator core, exhibit high power supply rejection, highly linear interpolation, a wide frequency range, and low-cost duty cycle correction.
