Clock redundancy is required for many of today’s data-communication, networking, and computer systems. Any interruption due to component or board-level failure, or even simply regular system ...

You know the basics about how the chip is clocked. Every microcontroller chip uses a clock, which keeps track of time for the chip, in general one assembly code instruction is run every clock cycle.

With more and more multi-frequency clocks being used in today's chips, especially in the communications field, it is often necessary to switch the source of a clock line while the chip is running.

We have featured quite a few cool clocks here at Geeky Gadgets, and the latest one is the work of Andrew O’Malley, the DOTKLOK, which is an open-source Arduino digital clock. The DOTKLOK comes with a ...

Before today, we probably would have said that scratch-built relay computers were the sole domain of only the most wizardly of graybeards. But this impressive build sent in by [Will Dana] shows that ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

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 ...

Circuit delay is increasingly affected by process variations at lower technology nodes. Global variations are in double digits now, and according to the International Technology Roadmap for ...
