    Charge electronic locks for shared bikes with the sun

    In large cities, the concept of “shared bikes” started several years ago. Anyone can rent a bike and return it to various docking stations throughout the city with a credit card. The rider is charged for the length of time that they’ve rented the bike. For example, in London, a shared bike user picks up and returns the bike to a fixed location, a docking-station kiosk like the one shown in Figure...

    Powering DDR memory in automotive applications

    Double-data-rate (DDR) memory enables high speed and performance in many electronic systems because of its ability to read and write on both the rising and falling edge of the clock. The ability to read and write data on both edges of the clock essentially provides two times the speed without increasing clock frequency and enables faster throughput in the system, as the central processing unit (CPU) can more quickly...

    Get the large-screen experience on the go with mobile smart TVs

    When viewing my favorite television shows, movies and sports, I subscribe to the theory that bigger is always better. The good news is that affordable large-screen TVs keep getting bigger, but consumers like me who crave that big-picture experience are often limited by wall space, room size and the eyesore of a massive TV. New display solutions called mobile smart TVs offer large images in stylish, portable packages....

    FRAM or flash: How to select the right MCU for your application

    When choosing a microcontroller (MCU) to use in your application, you will have to decide between using a device with flash or ferroelectric random access memory (FRAM). You might be wondering what FRAM is and if it’s a worthwhile feature. FRAM offers several advantages over traditional memory technologies such as flash, including faster write speeds, unified memory, low energy writes and there is no need for pre...

    Precise constant current regulation helps advance fast-charging

    With battery-operated devices now being an essential part of our daily life, the burden of charging these devices is receiving more attention than ever. A good number of new approaches have emerged in the last couple of years to address the long charging times to enable users to get their devices fully charged in minutes rather than hours. In this post, I’ll highlight trends in fast charging and the essential...

    LDO basics: noise – part 1

    In another LDO basics blog post , I discussed using a low-dropout regulator (LDO) to filter ripple voltage arising from switched-mode power supplies. This isn’t the only consideration for achieving a clean DC power supply, however. Because LDOs are electronic devices, they generate a certain amount of noise of their own accord. Selecting a low-noise LDO and taking steps to reduce internal noise are integral to generating...

    The road to today’s digital cockpit

    In my first car, there was only an AM/FM radio to keep me entertained as I relied on my own memory to get me from point A to point B. The instrument cluster was traditional, with only needles to estimate if I was driving at the speed limit or if I had enough gas for whatever small journey planned that day. Fast forward to today our lifestyles have become increasingly connected and car manufacturers are determined to...
