Latest Patents

One of his latest inventions is a digital duty cycle correction circuit. This circuit includes a duty cycle controller and a digital duty control code generator. The duty cycle controller generates first and second output clock signals by compensating the duty cycles of first and second input clock signals based on a digital duty control code. The digital duty control code generator creates the digital duty control code based on a frequency value obtained by converting duty cycle information of the first and second output clock signals.

Another notable patent is a semiconductor device designed to compensate for internal skew without the need for training with an external device. This semiconductor device comprises a signal generating unit that produces and outputs a reference signal, a first receiving unit that receives the reference signal and outputs a first output signal, and a second receiving unit that does the same for a second output signal. Additionally, it features a delay unit that delays the first output signal by a certain time, a sampling unit that samples the second output signal based on the delayed signal, and a skew controlling unit that manages the delay unit based on the sampling data.
