Keys to Enabling Advanced Future System Designs

Keys to Enabling Advanced Future System Designs

Abstract: Rated by PCNS 2019 Attendees as BEST keynote presentation In the past, system power budgets and data/operating speeds were wide and slow respectively. This allowed passive component selection and consideration to occur at the end of the design cycle. Today in the digital world, emerging single chip semiconductors now have enough processing power to become a real time – reconfigurable end system.

Protecting Implantable Medical Devices From Electromagnetic Interference

Protecting Implantable Medical Devices From Electromagnetic Interference

Abstract: The continuous advancement of medical device technology has led to a dramatic increase in the number of implantable devices that utilize onboard electronics. For example, devices used to treat cardiac arrhythmia — including pacemakers and implantable cardioverter defibrillators (ICDs) — frequently contain sensors to monitor heartbeats, onboard memory to record that data, processors to determine which therapy is required, and circuitry to generate either electrical impulses or shocks to correct the heart’s operation. In the U.S. alone, more than 300,000 cardiac arrhythmia devices — which include pacemakers and ICDs — are implanted each year. Neurostimulator implants – such as spinal cord stimulators, which are used to treat chronic pain – are also increasing as new products reach the market.

Base Metal Electrodes Reduce Size And Weight Of MLCCs In Satellites

Base Metal Electrodes Reduce Size And Weight Of MLCCs In Satellites

Abstract: The rate of change in the satellite world is accelerating and along with that comes the changes needed for power supplies onboard. This article provides a high-level view of the emergence of base metal electrode (BME) multilayer ceramic capacitors (MLCCs) for satellite applications. After providing some background on MLCCs and the development of their electrode materials, this article describes the advances in component materials, construction and fabrication techniques, and the track record in automotive and other sectors that have proven the reliability of BME MLCCs. Then the size advantages which motivate the use of these capacitors in space are discussed. The rest of this article reviews the reliability studies that AVX has performed to qualify BME MLCCs for space,

Evaluating Tantalum Electrolytics As Replacements For MLCCs In High Capacitance Applications

Evaluating Tantalum Electrolytics As Replacements For MLCCs In High Capacitance Applications

Abstract: Over the years, ceramic capacitors have been used interchangeably with tantalum in many applications, class II ceramics being the one electrostatic technology that can achieve the high capacitance values typically associated with electrolytic capacitors. But because of MLCC shortages, we are currently at a point where designers are reconsidering electrolytic capacitors for applications that had switched to class II ceramic in recent years. However, migrating circuit designs from MLCCs to tantalum electrolytics requires an understanding of multiple issues that impact how these different styles of capacitors will perform in the intended application. This article discusses the key parameters that differentiate these two capacitor categories in the various roles they play in power supply applications (bypassing, filtering, decoupling, bulk hold

Vital to life – MLCCs for safety-critical applications in harsh environments

Vital to life - MLCCs for safety-critical applications in harsh environments

Abstract: Electronic components in safety-relevant systems such as medical devices, aircraft controls, airbags or driver assistance systems must meet the highest requirements in terms of reliability and safety. This also applies to passive components such as ceramic capacitors.
