Latest Patents

One of Hwang's latest patents is the "Delta-sigma analog-digital converter and method." This invention provides a method to generate a digital output signal from an analog input signal. The delta-sigma analog-digital converter includes a loop input signal generating unit that creates a loop input signal based on both the analog input signal and a feedback signal derived from the digital output signal. Additionally, it features a noise shaping unit with multiple feedback loop stages that filter local error signals based on the digital output signal, resulting in a loop output signal with reduced noise. The quantizing unit then quantizes this loop output signal to produce the final digital output signal.

Another notable patent is the "Wireless power transmission apparatus and transmission method thereof." This invention describes a wireless power transmission apparatus that generates a wireless power signal for transmission. The apparatus operates using a magnetic resonance method to wirelessly transmit the generated power signal. It can also receive a reflection wireless power signal to determine the presence of a load apparatus and supply power accordingly. The wireless power receiver connected to the load apparatus receives the transmitted signal and reflects any remaining wireless power back to the transmitter, enhancing resonance characteristics without the need for a separate communication device.
