High-gain, high-bandwidth…why is this circuit oscillating?
Xavier Ramus
02 01 2013 02:51 PM
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...

TINA-TI Free Simulator Tool Make Amplifier Sims Easy
G Hann
02 11 2010 02:08 PM
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...

High-gain, high-bandwidth… how can I get it all?
Xavier Ramus
01 25 2013 10:27 AM
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...

Tips and Tricks for Minimizing EMI/RFI in your Circuit Design – a Great Tutorial from the Analog Apps Team
G Hann
01 22 2010 04:45 PM
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...

From the heart: How to simplify analog front end design for heart-rate monitors
Tony Calabria
02 12 2013 08:35 PM
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...

DAC Essentials: The pursuit of perfection
Kevin Duke
03 08 2013 01:10 PM
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...

Analog basics: Beginner knowledge and veteran refresher
Pete Semig
04 08 2013 12:36 PM
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...

DAC Essentials: String Theory
Kevin Duke
05 01 2013 09:48 AM
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...

Let’s take this driver out for a spin
Soufiane Bendaoud
05 10 2013 04:09 PM
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 amplifier...how do I make it work for me?
Xavier Ramus
04 26 2013 10:00 AM
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...
