Scientists from the University of Tokyo performed two-photon imaging in the visual cortex of marmoset monkeys to examine spontaneous and visual stimulus-evoked neuronal activities (top left). Visual ...
Data converters incorporate the common semiconductor noise sources such as, shot, avalanche, flicker, and popcorn noise. In addition, real data converter systems have errors that include quantization, ...
As a data converter supplier, we are sometimes asked, which is our lowest noise analog-to-digital converter (ADC)? While the tendency is to assume an ADC with the highest resolution would be the right ...
Many noise sources can plague high-speed radio-frequency (RF) analog signal chains, making design considerations that much more challenging. Both megahertz and sub-terahertz sampling-rate converters ...
European researchers have developed a new class of electronics that uses noise -- normally a problem -- as part of the signal. It means better, faster electronics. European researchers have developed ...
The National Radio Systems Committee recently published the results of a study on AM band noise. The report, principally authored by John Kean, is titled NRSC-R102, “Measurement of AM Band RF Noise ...
A signal-to-noise ratio (SNR) lets us express the relationship between signal and noise powers, as well as between the root-mean-square (rms) values of signal and noise voltages: SNR (dB) = ...
Separating the power/ground connections used for the analog sections from those used for the digital areas will improve the isolation of the power supplies. Adding external/internal filtering should ...
