It’s a very common challenge in circuits to need to convert an available DC source to a lower or higher voltage. For the high-to-low conversion, one option to use a low dropout regulator (LDO), but how to easily transform a lower voltage into a higher one? For AC voltages, the answer is well-known: use a […]
Many of the abilities that modern digital electronics enable rely on the fact that common processors can perform millions or billions of operations every second. This blindingly fast speed can make it appear that a device is handling many operations at once when in fact, it is rapidly following a sequential set of instructions, often […]

The “clock” function is a standard part of nearly every electronic system, with very few exceptions. Behind this simple-sounding, commonplace word, there is an array of complexity and subtlety in definition, performance, and design. Clocks are both vital and ubiquitous, so it is worth understanding the different functions they fulfill, they ways they can be […]

My previous blog touched on peak detect circuits. What seems simple in principle can be quite problematic if you want speed and accuracy. A diode and a capacitor makes a crude peak detect but the voltage drop of the diode makes it a poor choice so you will normally add an opamp to improve accuracy. […]
Current can flow in two different ways with respect to the load. Sensors often provide real-world, analog input for embedded applications. MCUs rely on sensors to be their electronic “senses” and actuators to physically interact with world. Interfacing with external devices requires some planning on the part of the designer to ensure efficient operation. One […]
An embedded system is much more than a computer, because they often must have a real time response and several constraints to work within a given system that is tailored by industry and function. Real-time operation requires a response to input within microseconds. Delays in responding, termed latency, are often unacceptable, especially in real-time systems. […]
“Smart” is frequently used as a prefix to mean new and improved for technology and even consumer type products. The term “smart sensor” has been used for over three decades (Giachino, J. M., “Smart Sensors,” Sensors and Actuators, Vol 10, 1986). Earning the smart prefix, meant the sensor performed a function that could not be […]
By Matt Smith, Head of Cortet Engineering. Colorado Offices As the Internet of Things (IoT) industry continues to expand, new information on emerging best practices, technical specifications and design considerations continues to flood the market. Here at CEL, one of our priorities is helping you navigate through the deluge of information and identify which technology […]
We have already looked briefly at Earth ground (if any), chassis ground, and commons (often misnamed as “grounds”). These do not exist as unrelated connections in a system. The issues related to connecting commons and ground is the subject of countless articles, academic papers, vendor application notes, anecdotes, and even books. There are many rules […]

During the first decade of this century, advances in several disparate technologies set the stage for a substantial rise in autonomous and semi-autonomous remote intelligent-node deployments that continues to this day. This trend arose in applications as different as hydrological surveying, transportation tracking and management, and machine health. It also has kicked off a flurry […]
