Title: Innovations of Jong-Won Choi
Introduction
Jong-Won Choi is a prominent inventor based in Seongnam-si, South Korea. He has made significant contributions to the field of frequency synthesis, holding a total of 11 patents. His work primarily focuses on enhancing the efficiency and functionality of electronic devices through innovative frequency control methods.
Latest Patents
Among his latest patents is a frequency synthesizer and method for controlling a frequency synthesizer. This invention features a voltage-controlled oscillator (VCO) that generates an output signal with a target frequency. The VCO is coarse-tuned according to a channel code derived through a binary tree search. The output signal can then be fine-tuned using a phase lock loop (PLL) circuit. Each stage of the binary tree search includes a comparison step to determine a channel code bit and a confirmation step to ensure that the channel code converges to a final code within an established range.
Another notable patent is a method for synthesizing frequency and the electronic device associated with it. This electronic device includes a bank changer that outputs a channel code corresponding to a reference frequency signal and a feedback frequency signal. It also features a channel code mapper that generates a changed channel code by applying an offset to the original channel code. The voltage-controlled oscillator in this device adjusts the total capacitance of multiple capacitors based on the changed channel code, allowing it to oscillate a frequency dependent on that capacitance.
