High-Resolution Wideband Continuous-Time ΣΔModulators

2016
The signal bandwidth of delta-sigma analog-to-digital converters has been greatly extended during the last few decades from a few tens of kHz bandwidth for audio to several hundred MHz to date for wireless applications. To enable a wideband and filterless RF radio front-end, high dynamic range and very high linearity of the wideband delta-sigma ...

High Resolution Digital Time Base

IEEE Transactions on Nuclear Science, 1979
A time base has been developed to supply general timing signals for the Cornell Electron Storage Ring, including beam bunch transfer triggers and beam detector triggers. The system consists of 8-bit counters and digital phase shifters of 8-bit resolution, under control of a data bus tied to the CESR control computer interface.

Radiation hardened high resolution timing generator

2015 IEEE Asia Pacific Conference on Postgraduate Research in Microelectronics and Electronics (PrimeAsia), 2015
A high resolution timing generator is used as a building block for Time to Digital Converters (TDC) and clock alignment functions. The timing generator is implemented using digital Delay-Locked Loop (DLL). As DLLs are vulnerable to single event effects, the propagation of single-event transients (SETs) single event transients (SETs) is a significant ...

Time-Domain High-Resolution Radon Transform

PGCE 2008, 2008
Multiple attenuation may be classified in two main methodologies; 1) Prediction of multiples from the data itself, and 2) utilizing moveout separation between multiples and primaries. A commonly used version of the prediction approach is the so called SRME technique, where surface related multiples are predicted from the data itself, and at least in ...

A high resolution time measurement system

[1991] Conference Record. IEEE Instrumentation and Measurement Technology Conference, 2002
A high-resolution, less than 1-ps, time measurement system (TMS) has been developed using a time-to-voltage (T/V) conversion interpolation technique. In order to accomplish the high-resolution measurement, the authors developed two specific techniques. One is the generation of an accurate interpolation pulse from the measured signal that is realized by

High-Time-Resolution Nuclear Magnetic Resonance With Nitrogen-Vacancy Centers

IEEE Magnetics Letters, 2016
We present a field-programmable gate array (FPGA)-based solution for high-time-resolution nanoscale nuclear magnetic resonance, with nitrogen-vacancy centers as a probe.

High resolution time-to-digital converters

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1992
Abstract High resolution TDC chips use active delays as time reference and flip-flops as comparators, instead of switched current sources and ADCs as implemented in analog designs. As a result, a straight encoding is obtained, allowing time binning down to 50 ps, taking advantage of the high accuracy of IC processes.

High-Resolution Optical Imaging from Trajectory Time Distributions

The Journal of Physical Chemistry B, 2006
Trajectory time distribution optical microscopy (TTDOM), which records the mean off-times of single molecular fluorescent indicators that light up when they collide with vesicles, is extended to record fluorescence durations or on-times. TTDOM can distinguish shapes of objects that are smaller than the diffraction limited resolution.

High-resolution surface-plasmon resonance real-time imaging

Optics Letters, 2008
We use surface-plasmon resonance in a silver film to obtain high-resolution real-time images of a transparent dielectric sample in contact with it. A new aspect of the work was the use of radially polarized illumination from a LED at 530 nm to obtain speckle-free images with high spatial resolution along all orientations.
