This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Intersil has upgraded its web based non inverting and inverting op amp design tools. iSim v4.1 is designed to select and simulate the optimum Intersil precision or high speed op amp device, resolve ...

Automating a flow into a semi-expert system requires a combination of parametric analysis and some judgment on required design issues and margins. This breaks the selection flow into a set of “must ...

The source that drives high-resolution analog-to-digital converters (ADCs) sees a high-frequency ac load and a dc load of a few hundred ohms or more. Thus, a high-performance op amp with high input ...

The Current Feedback Amplifier (CFA) burst onto the scene in the mid-1980s with the commercialization of this new topology by Comlinear Corporation. It quickly propagated industrywide with many ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

There are a number of reasons why an engineer would want to “split” a voltage rail in their design. Sometimes parts of the circuit, like a sensor or an IC, require a bipolar supply. Other reasons are ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...
