This One Is for All the Marbles
When I was a kid, my paternal grandmother lived at 453 East Exchange Street in Akron, Ohio. I remember that pale yellow and green house well, but one thing I remember most clearly is smaller: a shirt box in a...
The Aliens Are Going to Be Very Confused
Like many science fiction fans, I’ve been intrigued by the growing buzz surrounding Steven Spielberg’s upcoming film Disclosure Day. Details remain scarce, but the premise appears to involve one of humanity’s favorite topics: what happens when intelligent life from another...
In Praise of Natural Intelligence
For the past few years, we’ve all been captivated by a shiny new object: Artificial Intelligence. It writes emails. It summarizes documents or a Teams call. It generates code. It even creates passable country songs, which is either impressive or...
The Quiet Convergence of Power and RF
There was a time when power engineers and RF engineers occupied different ends of the hallway. The RF team debated noise figure and linearity as if civilization depended on it. The power team worried about volts, amps and whether something...
PSRR, A Measure of the Effectiveness of Filtering an Upstream Supply
In a previous part of this series on power integrity, we reviewed the meaning of Power Supply Ripple Rejection (PSRR) and in this and the following blogs, we continue to explore the subject. When choosing an LDO or linear regulator product,...
Line Regulation and PSRR (Power Supply Ripple Rejection)
In this part, we will review the performance of a VRM output with a changing input voltage, in this simple mathematical expression: ΔVOUT / ΔVIN The goal of this part is to link this “ΔVOUT / ΔVIN” performance in multiple...
Every VRM is a Power Amplifier (PA) of a Special Kind
Many engineers in the RF and signal chain fields think of a Voltage Regulator Module (VRM) system as a “power supply”, a totally different animal from their signal chain electronics components. Let’s find some common ground between RF/signal chain engineers...
Dielectric Resin Prints Millimeter-Wave Parts
Three-dimensional (3D) printing has captured the imagination of mechanical design engineers everywhere for its creative physical shape forming. Although design engineers may still be curious of the potential of 3D printing for electronic components, Rogers Corp. has little doubt that...
In Doubt if Your Antenna Placement is Optimal? Here are some things to consider:
•Vehicle Structure: Simulations should account for the car’s material and shape.•Antenna Type: Simulations help determine the most suitable type for the car’s requirements.•Ground Plane: The presence of a ground plane, typically provided by the car’s metal body, affects the antenna’s...
Simulation Saves Engineers From EMC Surprises
•EMC testing in simulation has become a popular method among engineers in the last decade. This technique allows for early detection of potential electromagnetic compatibility issues in a product’s development process. •By using simulation, engineers can test a product’s EMC behavior...
