Advanced Electronics: Understanding Design Challenges For Space Applications Part 2

Advanced Electronics: Understanding Design Challenges For Space Applications Part 2 In the previous article we saw that when a particle that hits a BJT with enough energy, part of this energy may get absorbed by the component and may create unwanted current between the emitter and the collector. If this issue is neglected, we may have some malfunctions. This phenomenon is called SEE (Single Event Effect). It is the responsibility of the designer to design the board in a way that will be SEE tolerant. As I wrote in the previous 阅读文章

Advanced Electronics: Understanding Design Challenges for Space Applications Part 1

Advanced Electronics: Understanding Design Challenges for Space Applications Part 1 Electronics design for space applications is a subject I’ve always been passionate about, and understanding the reasons particles can damage circuitry has always fascinated me. In this article, we’ll discuss how a Beta or Gamma particle can create—for a short period of time (usually referred as SEE or Single Event Effect)—a large current in your design which could lead to permanent damage if ignored. We’ll discuss a technique I have used in my 阅读文章

Understand the AC and DC Return Path on a High-Performance Mixed-Signal PCB

Understand the AC and DC Return Path on a High-Performance Mixed-Signal PCB High performance mixed-signal PCBs are difficult to design. Proper grounding and routing are essential to ensure accurate ADC conversion. In this article we’ll discuss a complex topic; the importance of designing a controlled current path on high performance mixed (Analog/Digital) PCBs, and how this impacts the performance of your board. What are we going to learn? • Loop currents follow different path (depends from their frequency range.) • How 阅读文章

How To Design the Perfect PCB Stack Up With Altium Designer

How To Design the Perfect PCB Stack Up With Altium Designer In the last 20+ years, electronics have become increasingly more complex. Board density is always being pushed to the limits, EMC/EMI regulations evolved and got stricter, and edge rates have become smaller. Therefore, the PCB Layout engineer needs a good understanding of EMC, PDN, EMI, and SI in order to route a modern PCB with confidence. In this article we’ll talk about some of the considerations we should have in order to create a PCB stackup 阅读文章
