Latest Patents

Seojin Choi holds a patent for 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 includes a replica voltage controlled oscillator (R-VCO) designed to intermittently cut off the power supply based on a reference signal. Additionally, it features a fundamental sampling phase detector (FSPD) that receives the output signal of the R-VCO as a reference for sampling and detects the phase error of a main voltage controlled oscillator (M-VCO).
