Latest Patents

One of his latest patents is titled "Variable-length clock stretcher with correction for digital DLL glitches." This invention involves a clock stretcher that incorporates a digital delay-locked loop (DLL) to derive delayed versions of an input clock signal. The combiner within the clock stretcher cyclically selects these delayed versions to generate a modified clock signal. It utilizes a hop code, which is dependent on a sensed condition, to determine the step size for the cyclical selection. The digital DLL is designed to correct its delay speed at discrete times, ensuring that any glitches incurred during speed changes are addressed effectively. This clock stretcher can operate from a sensed power supply without the need for intervening voltage regulation.

Another significant patent by Sang-Min Lee is "Methods and apparatus for improving remote NFC device detection using a low power oscillator circuit." This invention provides a method, apparatus, and computer program product for inductive communication, focusing on detecting a remote NFC device while minimizing power consumption. The communications device is equipped to monitor frequency oscillations associated with an NFC antenna using a calibrated low-power oscillator (LPO). It determines when the occurrences of frequency oscillations exceed a certain threshold and initiates an NFC polling procedure based on this determination.
