Most biochemical reactions accelerate as temperature increases, but our daily circadian rhythms, which are underlain by gene regulatory and biochemical networks, remain constant, even as temperatures ...

A novel technique for sampling clock recovery in a wideband networking waveform of a software defined radio is proposed. Sampling clock recovery is very important in wideband networking radio ...

Jitter is a short-term variation in the timing of a digital signal from its nominal value. There are two main types of jitter, random jitter and deterministic jitter. Random jitter is unbounded, that ...

Fig 1. In a typical PWM controller in which the active devices are driven by a simple square wave, a Fourier representation of the clock’s frequency spectrum consists of the fundamental switching ...

Hierarchical test methodologies are being broadly adopted for large designs. They provide roughly an order of magnitude better ATPG (automatic test program generation) run time, reduce workstation ...

As today’s designs become more complex, so too do their constraints. Design functionality typically gets a lot of attention – through code review, functional verification, etc. However, the ...

Clock-distribution devices create multiple copies of a master clock and distribute them to a variety of integrated circuits. They accept single-ended or differential clock inputs and supply multiple ...
