Bluetooth 5.1 SoC vs. Module: Which is Best for Your Design?
The list of features available in Bluetooth just got a little longer since the release of Bluetooth 5.1. Component manufacturers have taken this mobile technology to the next level for IoT devices by integrating wireless comms with an MCU for embedded processing. This is just another step in the continuous push to pack more functionality into a smaller footprint. If you want to incorporate a Bluetooth 5.1 SoC into your new product, you have two

How Copper Foil Roughness Affects Your Signals and Impedance
The history of engineering, both electrical and mechanical, is littered with approximations that have fallen by the wayside. These approximations worked well for a time and helped advance technology significantly over the decades. However, any model has limits on its applicability, and the typical RLCG transmission line model and frequency-independent impedance equations are no different. So what’s the problem with these equations? Senior PCB

PCB Mountable Connectors: SMD vs. Through-hole
When I designed some of my first boards, I was always working at DC or low speed, and any signal integrity problems from my connectors were an afterthought. These initial boards were for low frequency measurements of an electrochemical sensor. The only circuitry involved was a low-pass filter circuit with through-hole passives, a PCB mountable connector for a lab-grade power supply, and a parallel connection to an SMU. After learning the finer

Designing Pressure Tolerant Electronics: It's All About Mechanics
After a recent inquiry from a customer about a high power board that must withstand high gas pressures, my team suddenly realized we needed to do some research on designing pressure tolerant electronics. This area is not as popular as designing electronics for ambient pressures, but the design techniques used here enable important scientific expeditions and industrial applications in high pressure environments. Whether the board will be placed in

High Voltage SMPS PCB Layout to Minimize Heat and Noise
Whether you are performing AC-DC conversion or DC-DC conversion, switching power supply layouts are common in high voltage design and must be constructed carefully. Although this system is quite common, it will easily radiate EMI due to the fast changes in voltage and current during switching. Designers can rarely adapt existing designs into new systems as a minor change in one area can create an EMI problem that is difficult to diagnose. With

How to Select an Inductor for a Buck Converter
An SMPS is one of those quiet (yet electrically noisy) devices that makes your favorite electronics run smoothly. They sit in the background quietly doing their duty, yet your board wouldn’t operate without them. As part of DC-DC converter design for power-hungry applications, component selection is quite important for ensuring stable power delivery to a load with high efficiency. Among the numerous DC-DC converter topologies, a buck converter

How to Design Your PCB Test Coupon and What You Can Test
As the operating speed of components has increased, controlled impedance is becoming more common in digital, analog, and mixed-signal systems. If the controlled impedance value for an interconnect is incorrect, it can be very difficult to identify this problem during an in-circuit test. Minor mismatches may not cause a board to fail, but it can be difficult to pinpoint incorrect impedance as the cause of any test failure, especially if correct

Driving Haptic Vibration and Feedback in Wearables
Augmented reality, virtual surgery, limb replacements, medical devices, and other new technologies need to incorporate haptic vibration motors and feedback to give the wearer a full sense of how they are interacting with their environment. Unless these cutting-edge applications include haptic vibration and feedback, users are forced to rely on their other four senses to understand the real or virtual environment. Low cost components to support

Modeling Copper Foil Roughness in Altium Designer's Impedance Profiler
Advanced transmission line models for long interconnects require that designers include copper foil roughness calculations in order to determine accurate impedance. Without the right models or design software, you’ll be left to estimate the skin effect impedance, dispersion, and parasitics in your PCB. These models can be difficult to work with by hand if you’re not mathematically inclined, but the right design tools can be used to quickly

High-Speed Signal Routing: The 5 Important PCB Design Constraints
Your modern digital board is most likely classified as high speed, regardless of whether you looked at the datasheets for your components. Designing your board successfully will take some important steps when you begin your design. Aside from floorplanning and stackup design, your routing strategy will need to operate within some important PCB design constraints. After you capture your schematic as an initial layout and create an initial
