Cable equalization 101 – Automating your design
Hooman Hashemi
Judging by the number of views on a post related to numerical cable equalization , on the High Speed E2E forum (more than 3,700 at last count!), I would guess that it’s a pretty interesting topic for many folks. Since TI is one of the leading manufacturers of current feedback amplifiers (CFA),...

Filter for thought
Soufiane Bendaoud
Have you ever wondered how engineers designed active filters before the birth of software? They were able to do it using nomographs - but before we talk about what these are, let’s refresh our memory a little bit on active filters. Magnitude is the amplitude of the output. Phase is the angle...

Let’s take this driver out for a spin
Soufiane Bendaoud
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 amp. Depending on how low the power needs to be, I...

Being negative can still be positive
Loren Siebert 1
The first operational amplifiers (op amps) used what is commonly called split power supplies, meaning the power for the amplifier was symmetrical around ground with both positive and negative polarities. Since most power supplies used transformers to convert 120 V mains electricity, a simple center tapped...

Supercapacitors to the rescue
AmyLe
Monitoring the charging current of a supercapacitor application is very important. Without a precision current limiter, the charging current can overshoot when the voltage of the supercapacitor charges quickly, thus damaging the system. To prevent this, try this method to precisely limit the charging...

IAC or DIY? No, these aren’t stock tips!
Soufiane Bendaoud
IAC is what I call integrated analog circuits, some prefer AFE (analog front ends) while others would say IS (integrated solutions.) Whereas DIY has a universal meaning, “do it yourself!” So the question now is, are you better off with an IAC over DIY, and why? It depends on the application...

How to improve the startup and stop behavior of ERM and LRA actuators
Brian Burk
Eccentric rotating mass motors (ERM) and linear resonant actuators (LRA) are commonly used in smartphone and tablet applications to provide tactile feedback through haptic effects . While there are many characteristics to consider when designing for haptic feel, one of the most noticeable traits to users...

Reducing amplifier power consumption for SAR ADC drivers
Xavier Ramus
As power consumption in SAR ADCs gets smaller with every new device generation, the limitation in power sensitive applications becomes the amplifier. So how do we reduce power consumption further? Before looking at possible solutions, let’s consider the reason behind the reduction in power consumption...

Versatile tools to simplify your designs
Hooman Hashemi
In a world where electronics are moving to lower supply voltages, it is comforting to know there are still components around that can tolerate higher supply voltages specifically when it comes to operational amplifiers (op amps). Op amps are essential building blocks and the option to select a high...
