A Wind Sensor

[Editor’s note: This is the first in a series of articles derived from a session at this year’s ISSCC that focused on sensors and energy harvesting. The intent is that, in addition to highlighting some of the leading-edge work being done by the presenters, we can also bring some of the basic sensor issues to the forefront, since they are moving from the realm of the arcane to the realm of the everyday.]

One of the earliest images I remember of scientific equipment was the anemometer atop a barn. Such a … Read More → "A Wind Sensor"

Secure Foundations

In a world where attacks on electronic systems can be conducted remotely, security is a vital component of system design. Even systems that do not have to store personal or commercially confidential data now have to be designed with security in mind to prevent their core intellectual property (IP) from being copied and reused illegally. In these examples, we can see the two elements of electronic system security: design security and data security. Increasingly, the two depend on each other.

In what we call … Read More → "Secure Foundations"

Single-Event Upsets (SEUs) and Medical Devices

As process nodes for integrated circuits (ICs) continue to shrink, their susceptibility to single-event upsets (SEUs) due to high-energy particles rises. Specifically, it is the static RAM structures within these devices that pose the greatest concern. The awareness of these risks has long been known in the space community, and that knowledge has spread to other industries, such as networking, avionics, automotive, and now medical. Medical devices are not only susceptible to nature’ … Read More → "Single-Event Upsets (SEUs) and Medical Devices"

Power Supply Transients on RTAX-S and RTSX-SU Devices

Single-event effects (SEE) during operation of power regulators can cause the output of the regulator to be as high as the regulator input for short durations, on order of tenths of microseconds. Consequently, any device that is powered by the regulator could see this supply glitch during normal operation of the device. This report summarizes the experiments and data collected to study the impact of these power supply glitches on the RTAX™-S and RTSX-SU devices on printed circuit boards.

Next-Generation Packaging for CRM Applications

With smaller electronics, more options can be fit into the package, allowing for features such as RF transceivers for wireless communication, advanced sensors to optimally time pacing and defibrillation shocks and backup systems in case the main system fails. While integrated circuits (ICs) have taken advantage of advances in dense packaging, such as die stacking, in most cases the discrete components remain unchanged. Market pressures are now forcing improvements in the current discrete packaging.

Convenience Trumps Quality, Every Time

It’s not the features, stupid.

We all want to make better products. Hell, most of us would be happy just shipping the product at all, never mind making it better. A friend working at Philips Electronics likes to tweak the company’s cheery tagline, “Let’s Make Things Better,” with the simpler and more trenchant, “Let’s Make Things.” Sometimes the great is the enemy of the good. In other words, let’s just get this thing out the door and worry about improving it later.

Achieving High Performance DDR3 Data Rates in Virtex-7 and Kintex-7 FPGAs

This whitepaper describes various memory interface and controller design challenges and the 7 series FPGA high-performance solution that achieves a 1.866 Gb/s DDR3 data rate for Virtex®-7 and Kintex™-7 FPGAs.

FPGA-based systems frequently require an external memory interface to buffer data that exceeds the capacity of the FPGA’s internal memory. This memory interface can often dictate overall system performance because it must provide sufficient read/write bandwidth to keep up with the flow … Read More → "Achieving High Performance DDR3 Data Rates in Virtex-7 and Kintex-7 FPGAs"

Putting the User First?

A mathematics professor was in full flow in a post-grad seminar. The board was covered in formulas, and, as he finished writing an equation, he said, “And from this, gentlemen,” (it is a very old story). “And from this, gentlemen, it is obvious…” and his voice died away. He stood there for a few seconds and then he sat down for a few minutes. He left the room and returned after fifteen minutes. Picking up the chalk he resumed, “And from this, gentlemen, it is obvious that…” and wrote another equation … Read More → "Putting the User First?"

Using Low Cost, Non-Volatile PLDs in System Applications

The system market is comprised of applications in telecom infrastructure, computing, high end industrial and high end medical. Power supply sequencing, voltage and current monitoring, bus bridging, voltage level translation, interface control, and temperature measurement are typical board functions found in these applications. System designers are faced with continual pressure to meet their development schedules, and need to implement designs with minimal effort and risk while maintaining maximum flexibility. By using a programmable-based approach instead of several discrete devices or Application Specific Standard Products (ASSPs), designers can … Read More → "Using Low Cost, Non-Volatile PLDs in System Applications"
