Latest Patents

Choi's latest patents include an "Ultra-low jitter low-power W/D-band phase-locked loop using power-gating injection-locked frequency multiplier-based phase detector." This invention proposes an ultra-low jitter low-power phase-locked loop that utilizes a power-gating injection-locked frequency multiplier-based phase detector (PG-ILFM PD). The PG-ILFM PD features a replica voltage controlled oscillator (R-VCO) designed to intermittently cut off its power supply based on a reference signal. Additionally, it includes a fundamental sampling phase detector (FSPD) that detects the phase error of a main voltage controlled oscillator (M-VCO) using the output signal of the R-VCO as a reference.

Another notable patent is for an "Integrated circuit, electronic device including the same, and operating method thereof." This invention discloses an integrated circuit comprising a DTC block that processes reference and division signals to output new signals based on control codes. It also features a TDC that compares phases of signals, a digital loop filter, an oscillator, a delta-sigma modulator, and a probability modulator. The probability density functions of the control codes are designed to be time-invariant, enhancing the circuit's reliability.
