Analog Wire

  • 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...
  • 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...
  • I was checking out the TI E2E Analog forums this week and saw a number of EMI design based inquiries – it seems that a lot of us find ourselves struggling with the influence of EMI/RFI related issues. While we all know that it exists and can be...
  • My New Year’s resolution to get in shape hasn’t been as successful as I’d hoped. Like many others, I started strong but may have fallen off the wagon. During one of my workouts, I started wondering how hard it would be to design a...
  • In my last post, I introduced the DAC Essentials blog series here on Analog Wire . If you missed it, check it out here. While most IC designers I know would shudder to think of a datasheet this way, the purpose of a datasheet is typically to explain...
  • As a former college instructor who regularly lulled his students to sleep with a traditional lecture format, I’m excited to announce that TI is offering a “Hands-On Analog Basics” workshop at Design West 2013 (April 22-25 in San Jose...
  • No, I'm not actually going to talk about particle physics today - though that would be cool...instead we'll be discussing the theory of the string DAC architecture. String theory! The string DAC, sometimes referred to as the Kelvin divider...
  • Before I suggest a suitable op amp to drive an ADC, I look at the application. This steers me toward one of two categories: low voltage or high voltage. If the system requires a low voltage operation, chances are I’ll look for a low power op...
  • Current feedback (CFB) amplifiers mostly belong in the realm of high speed amplifiers . There are lot of good application notes developed over the years that describe the operation and the main issues encountered when applying current feedback amplifiers...
