Accurate Power-Efficient Format-Scalable Multi-Parallel Optical Digital-to-Analogue Conversion [PDF]
In optical transmitters generating multi-level constellations, optical modulators are preceded by Electronic Digital-to-Analog-Converters (eDAC). It is advantageous to use eDAC-free Optical Analog to Digital Converters (oDAC) to directly convert digital ...

Upregulation of transmitter release probability improves a conversion of synaptic analogue signals into neuronal digital spikes [PDF]
Action potentials at the neurons and graded signals at the synapses are primary codes in the brain. In terms of their functional interaction, the studies were focused on the influence of presynaptic spike patterns on synaptic activities.

Regulation of EGFR signal transduction by analogue-to-digital conversion in endosomes
An outstanding question is how receptor tyrosine kinases (RTKs) determine different cell-fate decisions despite sharing the same signalling cascades. Here, we uncovered an unexpected mechanism of RTK trafficking in this process.

Asynchronous SAR ADC with self‐timed track‐and‐hold
This paper presents an asynchronous SAR ADC featuring a self‐timed track‐and‐hold (STH) architecture. The design aims to address the common timing issue of divider‐based clock generation, where the fixed‐time track‐and‐hold (FTH) period often results in ...

Method of high timing resolution pulse synthesis based on virtual sampling [PDF]
Adjustable-width pulse signals are widely used in systems such as test equipment for hold time, response time and radar testing. In this study, we proposed a pulse generation method based on virtual sampling with ultra-high pulse width resolution. In the
