Analog Wire

  • Today, on the third anniversary of Bob Pease’s passing, I am recalling the many things that he was famous for. He was known and respected as a guru on band-gap voltage references and a magician with numerous analog applications tricks. He was a...
  • A revolution in sensing has begun! Today, TI announced the industry’s first inductance-to-digital converter (LDC), a true technology game changer for position and motion sensing. And I don’t say that lightly. This is the first post in a...
  • NTC thermistors and analog temperature sensors are two commonly used temperature sensing solutions that can be used for most electronic applications. Deciding which technology is the best fit for your application can be a difficult task. However, I’m...
  • In my last post, I discussed the string DAC architecture and its tendencies― if you missed it you can view that post here . This post will focus on two very similar architectures, the R-2R DAC and the MDAC. Recall that the big limitation of the string...
  • Modern day position sensing technology is incredibly reliable, low-cost, and simple to implement. What does it take? A 3-pin device and a small magnetic material! (actual size) Applications Hall effect sensing is all around us: Brushless...
  • There is a lot you can do with TINA-TI ; more than is obvious at first glance. This free electrical simulation software from TI is capable of unlimited nodes, it already has most of TI devices built-in and it can even run other manufacturer’s device...
  • When dealing with high speed amplifiers , it’s common to have unwanted oscillations because of parasitic or loop gain issues. It’s possible to predict the frequency range of these oscillations, but not to target a specific frequency. So how...
  • TI offers a free analog simulator on ti.com called TINA-TI and while there are definitely other tools out there that may be bigger - this one is fast and packs a punch. I found a great intro to the program (attached below) and spent some time with TINA...
  • Achieving high gain (1000-V/V or more) and high bandwidth (tens of MHz) simultaneously can be a challenge as we are forced to use multiple stages. Besides the circuit requirements of high gain and high bandwidth, the critical issues to pay close attention...
  • Last week we looked at achieving both high gain and wide bandwidth while maintaining sufficient signal-to-noise ratio (SNR) in “ High-gain, high-bandwidth…how can I get it all? ” In this post, we will look more closely at the implementation...
