Three Tips to Optimize a Device’s Battery Life
As more portable electronic devices with multiple features hit the market, battery run time becomes critical for product differentiation and customer satisfaction. Consumers frequently expect long battery life for their applications and devices. Long battery life is a major differentiator in consumer buying decisions. Devices with unexpectedly short battery life can damage a company’s brand, lead to decreased sales, and even cause a costly recall. And while batteries are inexpensive, replacing them is not. Replacing batteries often costs more than the mobile device. This white paper provides tips for maximizing the battery life of your smartphone or mobile device.

Practical Analysis of Backplane Vias
Accurate, verified models for vias in a multilayer circuit board are necessary to predict link performance in the GHz regime. This paper describes the methodology of using measurements on a test vehicle to build a high bandwidth, scalable model of long vias which includes the through and stub effects which can be used for system simulation. This simple model also provides valuable insight into the root cause of performance limits and how to overcome them.

DesignCon 2014 Mechanism of Jitter Amplification in Clock Channels
Jitter amplification in clock channels is analyzed analytically in terms of signal transfer function or channel S-parameters. The periodicity of the clock pattern eliminates the inter-symbol-interference jitter so jitter at the channel output is entirely induced by input jitter. A phase modulation (PM) approach is employed to derive the jitter transfer function and amplification factors for sinusoidal jitter (SJ), duty-cycle-distortion (DCD) and random jitter (RJ). Results demonstrate that jitter amplification is the consequence of smaller attenuation at the jitter lower sideband (LSB) than at the fundamental, which is at a higher frequency than the LSB. Scaling equations of DCD and RJ amplifications with channel loss is obtained by employing an exponential loss model. It is shown that jitter is amplified by lossy channels at any frequency below Nyquist and the effect grows exponentially with jitter frequency and data rate. Amplification factors of SJ, DCD and RJ are also derived within the square wave representation of clock signals, and the results are shown to recover those using the PM approach when high order harmonics are neglected. The theory is verified by simulations.

REST API for Test Automation and Lab Operations
Organizations today face a host of challenges to remain competitive. Their core goal is they want high quality products and services with faster time to market. To achieve that, they must test thoroughly and with effective repeatability. The solution is to be able to increase equipment utilization and automate, an in turn accelerate, everything in the testing process. One essential component of an effective test automation and lab operations solution is the caliber of the REST APIs (representation state transfer application interface) provided as components in the solution. This white paper examines the evolution of REST APIs, provides insight into the state-of-the-art of REST APIs, how they support continuous testing objectives in DevOps, and how they foster comprehensive automatability in testing.
