diverse applications such as user identification, interactive user interfaces with AR/VR devices, and self-driving cars. Direct time-of-flight (D-ToF) systems, LiDAR sensors, are desirable for long-distance measurements
ISSCC 2019 Session 30 Wireline I/O
A 140fsrms-Jitter and -72dBc-Reference-Spur Ring-VCOBased Injection-Locked Clock Multiplier Using a Background Triple-Point Frequency/Phase/Slope Calibrator
Seyeon Yoo, Seojin Choi, Yongsun Lee, Taeho Seong, Younghyun Lim, Jaehyouk Choi
generate low-jitter high-frequency signals, while using a ring VCO. In the sense that the VCO jitter is removed periodically by the reference clock, SREF, an MDLL also can be considered to be an ILCM. However, the most c
ISSCC 2018 Session 25 Wireline I/O
A -242dB FOM and -75dBc-Reference-Spur Ring-DCO-Based All-Digital PLL Using a Fast Phase-Error Correction Technique and a Low-Power Optimal-Threshold TDC
Taeho Seong, Yongsun Lee, Seyeon Yoo, Jaehyouk Choi
To improve efficiency in the use of silicon, there have been many efforts to develop ring-oscillator-based clock generators with low jitter. A PLL using a fast phaseerror correction (FPEC) technique [1] is one promising

have an ultra-wide bandwidth in a mm-wave band. A big challenge of a 5G transceiver is to generate ultra-low-PN (phase noise) local-oscillator (LO) signals to suppress integrated PN (IPN) over such an extremely wide band
ISSCC 2016 Session 10 Wireline I/O
A 185fsrms-Integrated-Jitter and -245dB FOM PVT-Robust Ring-VCO-Based Injection-Locked Clock Multiplier with a Continuous FrequencyTracking Loop Using a Replica-Delay Cell and a Dual-Edge Phase Detector
Seojin Choi, Seyeon Yoo, Jaehyouk Choi
An injection-locked clock multiplier (ILCM) is considered to be a promising solution that can generate low-jitter, high-frequency clocks, using a limited budget in terms of silicon area and power consumption. However, an
