As Lumens per Watt of LED is continually increasing, high brightness LEDs are widely adopted in today’s automotive lighting applications. Today, almost all interior and exterior lighting applications, even headlamps, are transitioning to LEDs.
Automotive lighting design engineers are now challenged to ensure high reliability, longer life span and optimal performance of the LEDs. An effective LED driving solution is crucial to achieving these targets. In this seminar, we will discuss the technical requirements and challenges for designing automotive LED lighting applications and how the latest PowerWise® LED solutions offered by National Semiconductor help overcome such challenges.

Since the very beginning of Switching Mode Power Supply, controller type solution with separated power switching devices means higher flexibility but much more design efforts. Not to mention the part of complicated loop compensation modeling and calculation. National Semiconductor's brand new constant ON-Time based Emulated Ripple Mode (ERM) regulation scheme provides an extremely cutting-edge and simple solution to design an efficient medium current step down power converter. This technology combines no loop compensation requirement, high efficiency, constant switching frequency, and stability over wide load range. In this presentation we'll be talking about how ERM works and how it benefits system hardware engineer's design with our new online design tools.

Have you ever had trouble designing a new sensor? If so, don't miss the chance to learn how to easily compare hundreds of sensors and complete your sensor path design with National's new online tool. In this webinar, we will go through a new tool with three simple steps: learn about and explore sensors, compare and select the best sensor for your application, and then design and build your solution. We will also share with you design tips and considerations that will support your time-to-market plans.

Designers for data acquisition systems are always facing new challenges from complex noise sources inside and outside of the systems. A lot of time and efforts have to be spent on removing the noise captured from various components of the data acquisition process: Operational Amplifiers, Analog to Digital Converters, Power lines and Digital Communication Interface and so on. In this webinar, we would like to share the techniques and solutions with design engineers on how to improve noise rejection, especially the EMI from the working environment of devices, e.g. Cell phone Signal, UHF, VHF¡­etc. We will also discuss from concept to real application our EMI rejection solution and how this solution simplifies data acquisition system designs.

Advanced OFDM (Orthogonal Frequency Division Multiplex) technologies impose additional challenges and requirements for testing new wireless communication devices and systems. This paper compares and contrasts traditional single-carrier modulation schemes with multi-carrier OFDM schemes to understand the test equipment and measurement considerations when using modern vector signal generators and analyzers. It covers in detail spectrum, power, and modulation quality measurements and techniques for R&D and high-speed production test applications. The paper covers testing of both SISO (single-input, single-output) and MIMO (multiple-input, multiple-output) communications systems used in 802.11n WLAN, 802.16e mobile-WiMAX Wave 2, which are also applicable to future LTE and UMB cellular standards.

In the past, FPGAs were typically low density and low performance—used primarily as "glue" logic to piece together a system. Today, FPGAs are high density, high performance components—used to implement major system functionality. Since the current trend is to use multiple FPGAs on a PCB, how do you effectively and efficiently integrate the two? New FPGA/PCB concurrent design processes and tools significantly improve system performance, product costs, and designer productivity. This session will discuss these new design approaches.

Decompensated amplifier is a unique type of amplifiers that provides higher bandwidth and faster slew rate. It has a minimum gain requirement. If you use the decompensated amplifier below the minimum gain stated on the datasheet, the amplifier becomes unstable. However, this limitation will not limit your design! It has many advantages if it is used correctly specially for high gain applications where the ratio of overall bandwidth to supply current is important! Other applications that would benefit from Decompensated Amplifiers are High Speed ADC Interface, Medical Systems, and Wide Band Communications. In this seminar, we will discuss the internal circuitry and why we can get higher bandwidth and faster slew rates with less supply current, its application, and compensation techniques when using decompensated amplifiers.

Backplanes are extensively used in many applications where signals from one module are exchanged with other module(s) within the system. Although the structure of backplanes is simple, there are many system design tricks hidden behind, especially when the data rate is high. This presentation will address most of the design challenges and explain how signal conditioning devices are able to ease the problems.
