Latest Patents

Among Dongmin Park's latest patents are two standout innovations: the "Phase interpolation-based fractional-N sampling phase-locked loop" and the "Differential digital-to-time converter for even-order INL cancellation and supply noise/disturbance rejection."

The first patent details a phase-locked loop (PLL) that includes a phase-frequency detector (PFD), a phase interpolation-based sampler, a loop filter, a voltage-controlled oscillator (VCO), and a fractional frequency divider. The PFD output signifies a phase error between a reference clock signal and a feedback signal. The PI-based sampler adeptly produces a slope signal based on the PFD output and makes adjustments according to a quantization error correction indication.

The second patent presents a method of quantization noise cancellation within a PLL. This method involves a phase detector receiving both a reference signal and a feedback signal, with specific time delays applied to each based on a delta-sigma modulator (DSM) error signal. This innovative approach allows for improved performance by effectively rejecting disturbances in the supply voltage that could affect the system's operation.
