    How level shifters enable the transition to low-voltage processors in industrial environments

    Consumer, computing, personal electronics, enterprise networking, automotive and industrial use cases are moving rapidly toward lower-voltage processor and microcontroller technologies. The advantages of lower-voltage processor-based systems – higher levels of energy efficiency, longer battery life, improved thermal performance, reduced production...

    Three ways to scale an analog input signal

    As electronic devices become more self-aware, the need for voltage scaling increases. I’m not talking about artificial intelligence, like Hal from “2001: A Space Odyssey. I’m referring to are electronic devices that have more self-checks, which entail reading many voltages of various ranges. Scaling an input voltage isn’t...

    Precision current measurement enhances electronic power-steering systems

    As vehicles become more electrified – not just electric vehicles or hybrid-electric vehicles, but even good-old gasoline/diesel power machines – it becomes more critical to accurately monitor the current consumed to ensure performance as well as long-term reliability. One area where this has become vital is in electronic power-steering ...

    The next-generation QFN: Do you have what it takes to use it?

    “I need it to be thinner, lighter, smaller ... and most of all, I need it to deploy a new, state-of-the-art manufacturing technology that defies the norm and revolutionizes how we make a product.” Does this sound like a CEO speech during the design kick-off of a next-generation smartphone or tablet? Sometimes new products are innovative...

    The dangers of deep snap-back ESD circuit-protection diodes

    As technology continues to progress, many technology companies are focused on squeezing more and more chipsets into smaller spaces. As a result, chipsets have continued to shrink in size since the invention of the integrated circuit. As chipset...

    Eye doctor: Reflections and how to deal with them in high-speed systems

    Welcome back to the “Eye Doctor” series! In the first installment , I highlighted the problems that can result from over-equalizing a signal. In this installment, I’d like to talk about another common signal-integrity issue: reflections and common ways to mitigate reflections. Transmission line theory tells us that reflections arise...

    What you need to know about transimpedance amplifiers – part 2

    In the first installment of this series , I described various factors that affect the loop gain of a transimpedance amplifier (TIA) and demonstrated how to compensate a TIA to achieve a Butterworth (maximally flat) closed-loop response. In this instal...

    RF sampling: linearity performance is not so straightforward

    **This is the 14th post in an Analog Wire RF sampling blog series . ** In my previous post, I discussed the impact of noise in radio frequency (RF) sampling architectures when receiving small signals to maintain sensitivity. Another determent to rec...

    Get Connected: Driving the development of CAN protocols at Plugfest

    Welcome back to the Get Connected blog series on Analog Wire. In my previous post, we explored the pros and cons of operating RS-485 links without any termination on the bus. With careful selection of the RS-485 device, you can eliminate the termination resistors from some buses, and thus remove the need to know the farthest reaches of the bus, making...

    Eight things to consider when choosing haptic feedback – part 2

    In the first installment of this two-part series, I discussed five things you should consider when picking a haptic driver and recent haptic advancements. To close this series off, we will cover the three remaining reasons. Closed-loop architecture As in most systems, closed-loop architectures are the most ideal designs. TI’s closed-loop...
