    The big noise about isolation is that we’ve made it small and quiet

    Some parts of a circuit work best when they can be forgotten. Designing distributed intelligence for control of sensing and actuation in noisy environments with our new isolation process is a great example. Circuit or galvanic isolation physically s...

    Inductor-free innovation: low EMI Class-D audio

    It would be a mistake to dismiss the ever-present television set as lacking innovation. According to the Consumer Technology Association (CTA), every year more than 200 million TVs are sold worldwide. Although overall the technology is mature, with low growth of 1-2% and dozens of competitors, the most innovative TVs, like 4K TVs, will grow at an amazing...

    Optimize the emissions performance in your isolated system

    “Emissions Impossible”! Emissions are inevitable when it comes to switching circuits. With circuits that have an external transformer for isolated power, you can increase the size of the transformer to proportionately reduce the switching...

    Applications of Low Voltage Differential Signaling (LVDS) in Multifunction and Industrial Printers

    Multifunction and Industrial printers often include a data path where an image must be passed between multiple boards in the system. This creates concerns for designers including noise immunity, electromagnetic interference (EMI), and power consumption over these links. In this post, I’ll take a look at how the different circuit boards in multifunction...

    Debugging an integrated ADC in a microcontroller using an oscilloscope

    You probably don’t reach for an oscilloscope first when debugging an analog-to-digital converter (ADC) integrated into a microcontroller (MCU). But an oscilloscope can help you make sure that the ADC operates as expected. In this blog post, I’ll use the C2000™ Piccolo™ F28027 MCU as an example to show you how. The precise...

    Transimpedance amplifier designs for high-performance, cost-sensitive smoke detector applications

    This post is co-authored by Collin Wells . Photodiode-based light sensing is a common technique where operational amplifiers (op amps) are used to condition a photodiode sensor for a wide range of applications. An example of this is in smoke detectors, where a photoelectric smoke alarm is used to identify the presence of smoke in the chamber. ...

    How to deliver clean USB Type-C™ signals

    The rapid growth of USB Type-C enables a unified interface to deliver data, video, audio and power through a single connector. USB Type-C ™ not only supports the latest USB data rate of 10Gbps, it also enables up to 100W power delivery through the same cable carrying the data traffic simultaneously. Type-C has reversible plug orientation; it also...

    How to implement FM modulation

    For most people, listening to frequency modulation (FM) radio is a part of their life. But what is FM exactly? It’s simply a popular modulation scheme used to embed information on a high-frequency radio carrier. The hardware requirements for im...

    Do-it-yourself: Three ways to stabilize op amp capacitive loads

    Capacitive loads can cause stability problems in operational amplifier (op amp) circuits, resulting in large overshoots, ringing, long settling times – and in severe cases, sustained oscillations. These issues occur because the capacitive load ...

    Big USB Type-C™ protection for your small application

    We’re starting to get used to seeing the USB Type-C™ connector on laptops and even set-top boxes, but as it makes its way into small form-factor applications like mobile phones, wearables or other portable electronics, system designers have different design considerations. Their challenge is how to take advantage of a world of new features...
