Low Resource FPGA Based Time-to-Digital Converter [PDF]

, 2016
For the precise measurement of the time difference between the arrival of different signals coming from the different channels, the time-to-digital converter (TDC) implemented in Field Programmable Gate Array (FPGA) is a very useful device.

A novel time to digital converter architecture for time of flight positron emission tomography

, 2013
Positron emission tomography (PET) is a molecular imaging technique that provides images of physiological processes inside the body. In clinical applications, PET image quality benefits from the time of flight (TOF) feature.

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.

An Adaptive-Resolution SAR ADC With Metastability-Sensing 1-bit TDC in 65-nm CMOS

IEEE Open Journal of Circuits and Systems
We propose a metastability-sensing one-bit time-to-digital converter (TDC) for a successive-approximation (SAR) analog-to-digital converter (ADC) that detects a metastability-specific current in the comparator, gates its clock to stop the conversion ...

Magnetoelectric Nanoparticles Enable Modulation of Cortical Networks by Low‐Intensity Static Magnetic Fields In Vitro

Advanced Science, EarlyView.
Neuromodulation strategies are increasingly needed to stimulate, restore, or replace altered neuronal activity in disease. Cobalt ferrite‐barium titanate (CFO–BTO) magnetoelectric nanoparticles convert low‐intensity static magnetic fields into local electrical modulation of cortical networks.
