Latest Patents

One of his latest patents is a digital phase locked loop device and method in a wireless communication system. This invention includes a Digitally Controlled Oscillator (DCO), a divider, a Phase Frequency Detector (PFD), a Time to Digital Converter (TDC), a delay comparator, and a level scaler. The DCO generates a frequency signal based on an input Digital Tuning Word (DTW). The divider divides the frequency signal at an integer ratio, while the PFD generates a signal representing the phase difference between a divided frequency signal and a reference signal. The TDC measures the time interval of the phase difference, and the delay comparator calculates a time interval when rising edges coincide. The level scaler generates a DTW that operates the DCO using a digital code representing the time interval.

Another notable patent is a Time-to-Digital Converter (TDC). This TDC includes a first TDC unit that receives two input signals and delays the first input signal on a specific time basis. It generates first phase-divided signals by performing phase division on signals of input/output nodes for each of the first delay blocks. The second TDC unit delays a phase-divided signal closest to the time-amplified second input signal, generating second phase-divided signals through a similar process.
