Title: The Innovations of Seong-Ho Lee - A Visionary Inventor from Aliso Viejo, CA

Introduction

Seong-Ho Lee is a distinguished inventor based in Aliso Viejo, California, recognized for his contributions to advanced technologies with five patents to his name. His innovative inventions have significantly impacted the fields of phase interpolation and digital-to-analog conversion, showcasing his expertise and ingenuity.

Latest Patents

One of Lee's latest patents is titled "INL detection and calibration for phase-interpolator." This apparatus includes control logic that is coupled to a phase detector circuit and an adjustable delay circuit. The control logic is designed to obtain the state of the first phase of an output signal from a phase interpolator relative to a second phase of a reference signal. It can adjust the delay of the reference signal until both phases align perfectly. Additionally, the control logic accurately measures the total delay of the reference signal when they match and determines the integral non-linearity of the phase interpolator accordingly.

Another of his recent innovations is the "Pre-driver peaking technique for high-speed DACs." This pre-driver circuit features a differential input circuit to receive a differential-input voltage. A latch circuit is integrated into the design to latch voltage levels at a differential output port, allowing enhanced peaking of output voltage signals to facilitate high-speed operation of both the pre-driver circuit and any connected digital-to-analog converter (DAC) driver circuit.
