This white paper will explore the optimization of PCB layout for an eGaN FET based point of load (POL) buck converter, comparing the conventional designs and proposing a new optimal layout to further reduce parasitics.
The optimal layout will provide improved efficiency, faster switching speeds, and reduced device...

The use of power supplies in harsh, remote environments brings with it many fundamental design issues that must be fully understood if long-term reliability is to be attained. For designers of communications equipment downtime is not an option. Both revenues and safety can be compromised under such circumstances.

Type-C interfaces bring dramatic benefits to consumers. However, in order to realize this potential designers must implement Type-C's Power Delivery (PD) protocol, detect cable orientation and switch high speed signals, as needed and, if desired, provide support for Vendor Defined Messaging (VDM).
This whitepaper...

Many moderate size Programmable Logic Device (PLD) designs, especially those in control plane applications, consist of a number of interfaces interconnected via an onchip bus to a microprocessor that may be on- or off-chip. Although each interface is often relatively simple, the task of building all the on-chip interconnections...

Vector Network Analysers (VNA) are gaining popularity in the Signal Integrity community as Time Domain Measurement and Analysis tools.
VNAs with 8 ports or more can provide significant decreases in test time by migrating from a 4-port measurement system to an 8-port measurement system. For tight tolerance DUTs...

This paper will give an overview of both high and low throw-count RF switches used in different circuit locations in a typical mobile device design, and discuss how each performance specification and design feature will impact on the overall performance of your system. In addition, this paper will dive deeper inside each...

Most NAND Flash based 2.5” SSDs have RAM caches for high IOPS, the contents of which take multiple write cycles (written to flash) to store safely. One of the disadvantages of this scheme is that the extra RAM memory and supercaps add to the physical space, cost and unreliability of the product (compared to Swissbit...

Deembedding, often a necessary and complex task, is made easier with an integrated hardware and software solution. Whether you are debugging a high-speed interface such as DDR or PCIe, characterising a fast clock or analysing a complex RF signal, you want to see the real signal and not artifacts of the test setup such...

Most often capacitor selection to the uninformed seems
like a simple choice but the demands, challenges and
expectations of modern electronics prove otherwise. As
more electronic systems continue to be integrated into
our automobiles, the need for capacitor technologies that deliver high reliability, long life,...

It is much lower cost and causes far fewer problems to use a single power converter correctly rated for the application rather than two or more in parallel. However, there are power converters which feature master slave parallel operation. These units are intended for modular expansion schemes and fault tolerant parallel...

Flash memory is commonly used to store firmware in embedded systems. Occasionally, the firmware stored in the Flash memory in some systems is accidentally corrupted, preventing the system from booting up after power-on. Flash corruption is commonly associated with a software bug. However, it is also commonly understood...
