    Power Tips: Automotive EMI Series: Dithering? Not always a bad thing

    An automobile design engineer approached our team recently with an issue: he was unable to meet the Comité International Spécial des Perturbations Radioélectriques (CISPR) 25 Class 5 electromagnetic interference (EMI) standard during conducted EMI measurements for a fixed-frequency buck regulator they designed. Let me briefly go over some of the aforementioned EMI terms: EMI is the unwanted...

    ‘Agribot’ enhances fine wine with high tech

    In an innovative blend of fine wine and high tech, a robot developed by students under the direction of a Kilby Labs researcher someday may help wine-growers and other farmers protect their crops from disease. Built on a plywood platform mounted atop wheels from an old electric wheelchair, the agricultural robot – or agribot – is designed to drive up and down rows of vineyards to spray fungicide that will...

    High-voltage power innovation: Past, present and future

    There are two things that I look forward to everyday: the people I get to work with, and the technology I get to play with. But I sometimes like to take time out to reflect on how far the industry has come in high-voltage innovation, and think about what we’ll see next. Because my team is helping to drive innovation in high-voltage power conversion, I have a front-row seat to witness how our customers take advantage...

    Disentangling RF amplifier specs: amplifier spot noise vs. noise figure

    In the world of high-speed amplifiers, noise is commonly represented one of two ways. For radio frequency (RF)-oriented amplifiers, such as low-noise amplifiers (LNAs), radio frequency power amplifiers (PAs) and RF gain blocks, noise is usually given as a noise figure value. For high-speed operational amplifiers (op amps) and fully differential amplifiers (FDAs), noise is typically represented as voltage spot noise, which...

    Energy harvesting solutions enable expanded 4-20mA current loop functionality

    Sensing and measurement is becoming more and more important in the industrial sector. From both a factory and process automation standpoint, sensor transmitters are being added to improve system intelligence, detect faults and drive efficiency. In process automation specifically, 80 percent of the sensors have a HART 4-20mA interface. Current loops are ideal for data transmission because of their inherent insensitivity...

    When to use load switches in place of discrete MOSFETs

    Before people knew about electricity, they used candles for light. While this was a common way to see in the dark, the invention of the light bulb proved to be a better solution. Much like a candle, the most common approach to switching a load is to use a power MOSFET surrounded by discrete resistors and capacitors (and a bipolar junction transistor (BJT)/second FET for controlling the power MOSFET). But in most cases...

    Power Tips: Multiphase supplies can save space

    When I started at TI, one of the first power supplies that I worked on was a high-current two-phase buck power supply for a processor core. The current was 40A – pretty large at the time, and too high to implement in a single stage. Most power-supply designers look to multiphase applications to split up high-current rails into stages that are more manageable in terms of power dissipation and size. You can also apply...

    The top 6 challenges facing IoT – and how we are overcoming them

    Smart homes. Connected cars. Intelligent factories. At the heart of all of these clever technologies is an interconnected network of devices known as the Internet of Things (IoT) . The IoT is headed for a tipping point. By some estimates, there will be 50 billion ‘things ’ communicating with each other or the Internet by 2020. So a challenge lies before us: How do we make the IoT easy to use, cost effective...

    Pump it up with charge pumps – Part 1

    Life was simple when I first became interested in electronics. Components were so big I could solder them without a microscope. Switching converters switched at a whopping 25 kHz, digital circuits all used a 5-V supply voltage and all the computers I came across used the RS-232 serial interface to communicate. The RS-232 standard specifies that a logic 0 is represented by voltages between 5 V and 25 V, and a logic...

    Selecting the right inductor for ultra-low distortion Class-D audio amplifiers

    Selecting the inductance value for the output filter of a Class-D audio amplifier is always a critical design decision. With next-generation ultra-low-distortion Class-D amplifiers, selecting an inductor with poor electrical properties can severely limit the audio performance. My colleague Brian talked about how high-definition audio is changing the way we listen in his December blog post . In this post, I’ll discuss...

    Top three reasons to include proximity sensing in your human interface design

    One of the benefits of automating control systems within buildings is the ability to customize services and personalize a user’s environment; the human machine interface (HMI) is the gateway to such controls. The addition of proximity sensing is an underutilized improvement to many interfaces in an automated building ecosystem, including thermostats, security-system keypads, monitors and elevator call buttons.
