Latest Patents

One of Ki-Jin Kim's latest patents is an analog-to-digital converter. This innovative device includes a first latch row corresponding to a first stage, a second latch row for a second stage, and a digital processor that encodes output signals from the second latch row to generate a digital signal. The first latch row consists of multiple first latches that receive an analog input signal and reference voltages, operating in synchronization with a first clock signal. The second latch row features several second latches that receive output signals from the first latches and operate in synchronization with a second clock signal, which is delayed from the first reference clock. Additionally, it includes third latches that utilize an interpolation technique to enhance performance.

Another significant patent is a phase-locked loop based frequency synthesizer and method of operating the same. This synthesizer generates multiple output reference signals by phase-delaying an input reference signal and creates comparison signals using a frequency divided by a fractional frequency divider. The comparison signals are lower than the divided frequency. Furthermore, the synthesizer controls the output frequency of a voltage-controlled oscillator through phase and frequency comparison between the output reference signals and the comparison signals.
