The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall clock ...

As consumers thirst for the high-definition experiences delivered by expanding amounts of signal bandwidth, design challenges related to clocking become increasingly difficult and complicated. The ...

Clocks are the heartbeats of embedded systems, providing timing references and synchronization between components, subsystems, and entire systems. Incorrect clock signal amplitudes and timing can ...

With the advances of highly phase coherent lasers, optical atomic clocks containing multiple atoms have demonstrated stability that reaches the standard quantum limit (SQL) set by the available atom ...

Physicists in Germany have sent a burst of light over a distance of 920 km down an optical fibre – with its frequency remaining stable to the 19th decimal place. As well as supporting the development ...

This circuit transforms a pulse-width-modulation (PWM) signal into non-overlapping clock signals, whose number depends on the length of a shift register. These clock signals can be used to power up ...

At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it’s fraught with the most problems at the ...

Clocks are power- and area- hungry, and difficult to distribute in a controlled manner. What is being done to reign in these unwieldy beasts? The synchronous digital design paradigm has enabled us to ...

This paper presents a low power Clock Gating scheme for clock power improvement that reduces power dissipation by deactivating the clock signal to an inactive value (for clock gating cell) when clock ...
