Title: Jiayun Zhang: Innovator in Phase Interpolation Technology
Introduction
Jiayun Zhang is a prominent inventor based in Thousand Oaks, CA (US). She has made significant contributions to the field of phase interpolation technology, holding a total of 3 patents. Her work focuses on developing high-performance phase interpolators that enhance the functionality and efficiency of electronic systems.
Latest Patents
One of Jiayun Zhang's latest patents involves an apparatus designed to implement several high-performance phase interpolators. This invention includes a full-wave integrating phase interpolation core that comprises two pairs of in-phase and quadrature-phase current DACs arranged in a cascode architecture. These components work together to drive an integrating capacitor and produce an interpolation voltage waveform. The current DACs are meticulously biased, weighted, and controlled by in-phase and quadrature-phase input clocks, resulting in an interpolation waveform that presents a phase value between the phases of the input clocks. Additionally, some embodiments of the interpolator core utilize feedback circuitry and reference voltages to adjust the common mode and amplitude of the interpolation voltage waveform. This ensures optimal performance and operation within the interpolator's linear region or output compliance range. Both single-core and dual-core implementations, along with other variations of the interpolator core, demonstrate high power supply rejection, highly linear interpolation, a wide frequency range, and low-cost duty cycle correction.
