Integrated Device Technology (IDT)

When normal interference occurs, reception of part of a transmitted packet of data may be interrupted due to an overlap in the Bluetooth and 802.11 b/g signals, resulting in packet errors. Closely located antennae can cause front-end overload interference on the second system running. However, this interference requires a stronger interfering signal and is therefore a less common problem than normal interference.

Introduction With the advent of new nomadic devices (SmartPhones, PDAs, laptops) and multimedia applications, the requirements for wireless connections are shifting from simple data rate increases to complex and heterogeneous Quality of Service (QoS). And as these devices are battery-powered, the performance requirements come with a severe constraint on energy consumption. This results in a continuously growing gap between the available energy—constrained by the battery technology—and the steeply increasing energy requirements of emerging radio systems. Technology scaling, platform improvements and circuit design progress are not sufficient to bridge this gap; there is a need for holistic system-level strategies. In this article, we advocate a two-step approach. First, energy-scalability is introduced in the design of the radios. Secondly, intelligent run-time control is introduced to enable low power operation, by exploiting this scalability as well as the dynamics in the system. As a result, software defined radios (SDR) can be realized achieving a power consumption which can be comparable with dedicated radio implementations.

Lies, damn lies and op-amp models Op-amp vendors don't supply you with the transistor-level circuits of their products; that would give their secrets away to the competition and would demand a great deal from your simulator if you were, for instance, analysing a filter with 12 op amps, each with 70 or more transistors. They provide 'macromodels' which aim to replicate all the essential behaviours of the real device using as few nodes as possible, for faster running. These models are supposed to be much more accurate than the very simple amplifier archetype which I used in part 3 to demonstrate some home truths about amplifiers.

A key challenge in power gating is managing the in-rush current when the power is reconnected. This in-rush current must be carefully controlled in order to avoid excessive IR drop in the power network as this could result in the collapse of the main power supply and loss of the retained state.

Planar vs. trench MOSFET: key parameters for load switch When choosing a MOSFET, the first parameter the designer should usually consider is the on-resistance between Drain and Source while the MOSFET is ON (RDSON ). This is because several of the key performance requirements for power switching, including low voltage drop, high current capacity between VIN and VOUT (ID ), and lower power dissipation (hence higher efficiency), are directly related to the RDSON . Since load switches typically handle more than 1 A peak current, it is desirable to have a RDSON that is as low as possible, and no higher than 100 mΩ, to achieve the lowest voltage drop and highest efficiency. Since a trench MOSFET typically has higher cell density (up to 50 percent) than a planar MOSFET, its RDSON tends to be lower by about 15 percent when compared its planar counterpart with similar die size.

DSP libraries Hand-optimized assembly code can offer up to ten times as much performance as compiled code. However, writing hand-optimized assembly is a difficult and time-consuming process. This makes the availability of DSP libraries critical to the software development process. With the right libraries, the developer can achieve assembly-code performance with the same effort as writing C code.

In the most general sense, they all provide some level of metadata support along with the ability to store AV media content. The pipes in this diagram illustrate this.

For the purposes of discussion, the first step is to create a quick reference metric that will help evaluate potential improvements in response times and flexibility, but it should be limited to the objectives of the engineering department. If our metric demonstrates opportunities to reduce the time it takes to implement an idea without increasing the cost, we would likely take those opportunities. For other cases, if we can quantify the cost increase for this response time reduction, marketing and management can provide their input to decide if it is a worthwhile opportunity to pursue.
