A 100–750 MS/s 11-Bit Time-to-Digital Converter With Cyclic-Coupled Ring Oscillator

IEEE Access, 2021
This paper presents the first measured cyclic-coupled ring oscillator (CCRO) time-to-digital converter (TDC). The CCRO realizes a robust true time-domain delay interpolation with sub-gate-delay resolution.

TDC with 1.5% DNL based on a single-stage vernier delay-loop fine interpolation

, 2013
We present a compact TDC Module based on the Time-to-Digital Converter ASIC fabricated in 0.35 μm CMOS technology. This chip measures the time-interval between two inputs, called START and STOP, with a 10 ps resolution when using a 10 ns reference clock.

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

EcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...
