At their core, CDR circuits combine elements such as phase detectors, digital loop filters and voltage-controlled oscillators, to reconstitute a reliable clock signal from sometimes noisy or ...

That hasn’t stopped companies from trying to reinvent the alarm clock for the connected era, and Circa, a new Kickstarter project from Circa Labs, seems like one of the nicer attempts at the idea.

Among the most critical components are clock generator circuits, which require low phase noise and low jitter for high-precision operation. Challenges in Clock Generator Design Jitter is one of the ...

In theory, synchronous clock multiplication is an easy task. A simple PLL with two digital dividers—one inserted just after the VCO (voltage-controlled oscillator) and the second one placed directly ...

The design is a bit of a departure from [Gislain]’s previous circuit sculpture clock, but it’s just as beautiful, and equally as mind-boggling in terms of construction difficulty.

Here is an ultra simple automatic light switch circuit for bedrooms. After construction, connect the input terminals of this circuit in parallel to the internal buzzer terminals of a Quartz-Alarm ...

Smooth switching to a redundant clock source upon detection of a missing clock can avoid interruption of system operation.

Description of a circuit that uses 4 flip-flops and a gate to detects clock failures by monitoring a second clock signal. Has advantages over conventional approach that employs silicon delay lines ...

When dealing with clock circuitry in processor and bus design, there are several design issues that must be overcome. One of the main design issues in all applications is providing low phase noise or ...

Freeform circuit sculptures are a perfect example of the realm where electronic meets art. While many of these objects only serve aesthetic purposes, [Zachary Goode]’s X-Wing clock satisfies … ...

Toward a system-level understanding of this transcriptional circuitry, we identified clock-controlled elements on 16 clock and clock-controlled genes in a comprehensive surveillance of ...

Clock ticking for Circuit City's survival Bankrupt electronics seller says it has until next week to reach deal with 'potential' buyers for its business or else it may have to start liquidating.
