    How to detect insulation failures in electrical equipment – part 2

    In my last post , I emphasized the importance of insulation in electrical equipment. In this post, I will describe another method to measure the leakage current through the insulation resistance. Figure 1 is a high-level block diagram of this method, which entails applying a fixed voltage (500V, generated using a high-voltage DC/DC converter on a...

    Keep it simple with an LDO regulator

    Living and working in Asia exposes me to a wide variety of interesting support questions. For example, I was recently asked if TI had a cross-device to an LDO controller. This controller is in a small-outline transistor (SOT)-236 package that takes up a 3mm-by-3mm area on the printed circuit board (PCB). Figure 1 shows the recommended schematic for...

    It's in the math: how to convert an ADC code to a voltage (part 2)

    In part 1 of this series , I explained how you can calculate the input voltage to an analog-to-digital converter (ADC) by multiplying the ADC’s output code by the least-significant bit (LSB) size using Equation 1: To calculate the ADC’s LSB size, we used Equation 2: Now that you know how to calculate the input voltage from the...

    Designing for tomorrow, today: How advanced light control changes the game across industries

    Today, the range of applications and markets where advanced light control technology helps solve complex engineering problems is incredibly broad. This wasn’t always the case. Back in the late 1980s, the digital micromirror device (DMD) technology we invented was still in its infancy. Ideas like 4K digital movie projection or 3D industrial...

    Striking white gold: Bavarian farm uses smart agriculture to accelerate asparagus season

    The delicate flavor of white asparagus signals that spring has come to Bavaria – much like bluebonnets herald the spring in Texas. This year, the asparagus season – or Spargelzeit – came four weeks early in Germany thanks to a smart...

    Charge it up with charge pumps – Part 4

    To conclude this short series on charge pumps, I’d like to give you a few circuit ideas, to get you thinking about a basic charge-pump circuit as a building block adaptable to a wide range of applications. If your application needs a nonstandard solution, there’s a good chance you can cobble it together from a few simple components. Each...

    The secret of using noise to improve your ADC’s performance

    Have you ever found an analog-to-digital converter (ADC) for your application and later realized that you needed higher effective resolution? If you have noise in your system or can add noise to your ADC input signal, you may be in luck. Oversampling the signal can increase the effective number of bits (ENOB) of resolution for the ADC, but this requires...

    Digitally select your reference voltage

    Adjustable voltage references offer great flexibility to circuit designers because the reference is not limited to the manufacturer’s pre-set values. The adjustable output is typically configured with a voltage divider from the output to the fe...

    Three steps to select a protection diode to protect high-speed interfaces from ESD strikes

    USB and High-Definition Multimedia Interface (HDMI) have had an overhaul in the last three years that increased the data rate and throughput of these protocols. Data rates have grown to 6Gbps for HDMI 2.0 and 10Gbps for USB Type-C USB 3.1 Gen 2. This...

    From blue light to green power

    Whizzing across the Japanese countryside at 300kph, my colleague Tomomasa Emoto and I arrived at Nagoya station by Shinkansen. Nagoya is home to famous Shintō shrines and castles, but that is not why we were there. We had the pleasure of visiting Professor Hiroshi Amano at Nagoya University. Amano-sensei won the 2014 Nobel Prize in physics, along with...

    Engineers do better than magicians: HMI touch through a thick glass

    Giovanni Campanella and Matthieu Chevrier co-authored this post. Magic tricks are great for impressing friends and family; they just don’t tend to contribute to innovation among our industrial customers. Even so, a t TI we have developed what sounds like a magic trick: a way to put a human hand “through” thick glass. In process...
