The number of electronic systems in cars has increased in recent years, reaching higher levels of complexity with the adoption of new technologies for infotainment and advanced driver-assistance systems (cameras, radar, lidar, etc.), along with multiple sensors for many different purposes (stability, speed, acceleration, etc.). In such a landscape, there is no easy answer to the need for a high bandwidth, low latency, deterministic, robust, and cheap communication bus. This paper examines the use of A2B® and Ethernet in Automotive Applications.

The processing power of FPGAs, SoCs, and microprocessors continually increases, resulting in increases in power requirements. This article considers the LT8652S is a current-mode, 8.5 A, 18V synchronous Silent Switcher® 2 buck regulator as a key solution.
We are experiencing an explosive growth in demand for bandwidth that pushes the carrier frequencies to multiple decades of gigahertz. However, as the frequencies increase, the instrumentation solutions targeting these devices and frequencies can become extremely complex. In this article, we review several methods for low phase noise signal generation and demonstrate the advantages and disadvantages of these methods. We introduce the translation loop device, which takes the best of all frequency generation methods without their complexity to enable ultralow phase noise signal generation.
Designing the correct power source is essential and complex, since there is no one typical application. While total automation of power supply design is yet to be achieved, a comprehensive range of semi-automated tools are available today. This article details the use of semi-automated design tools through five critical steps of the power supply design process. These tools can be valuable to both the novice and expert power supply design engineer.
The promise of a fully autonomous tomorrow no longer seems like a pipe dream. Today, the questions around autonomy center on the underlying technologies and the advancements needed to make autonomy a reality. Light detection and ranging (LIDAR) has become one of the most discussed technologies supporting the shift to autonomous applications, but many questions remain.
Lithium-ion (Li-Ion) batteries are a popular way to store energy in electric and hybrid vehicles. These batteries offer the highest energy density of any current battery technology, but to maximize performance, a battery monitoring system (BMS) is mandatory. A state-of-the-art BMS not only allows you to extract the highest quantity of charge from your battery pack, but also lets you manage the charge and discharge cycles in a safer way, which results in an extended life.
It is more important than ever to design medical devices that are more convenient and less power hungry. This article covers the fundamentals of SpO2 measurement and demonstrates how a new generation of optical analog front ends (AFEs) can help create a better oximeter. The new devices can have reduced design complexity, a reduced burden on the mechanical design, and decreased power consumption.
This article explains continuous-time sigma-delta (CTSD) ADC technology in a less traditional approach, enabling signal chain designers to envision a new class of easy-to-use precision ADC technology as a simple system that interconnects a few well-known components. In Part 1, we highlighted the key challenges of incumbent signal chain designs that can be simplified with a precision CTSD ADC, as it maintains continuous-time signal integrity while achieving the highest precision. Now, the question is what’s behind the CTSD architecture that enables it to achieve these advantages?
