An optimal way to determine an op amp's input capacitance. Steps involved in making the input-capacitance measurement. 1. With a series resistor at the op-amp input, the input capacitance of the op ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

I ask these types of questions frequently. Do we need another “widget” when everybody and their grandmother makes one of these nowadays? Well, I have not seen any other amplifier that can beat the ...

If you didn’t know better, you might think the phrase “class A amplifier” was a marketing term to help sell amplifiers. But it is, of course, actually a technical description of an amplifier that ...

Texas instruments has revealed a buffer amplifier developed especially for oscilloscope inputs from dc to GHz. Texas instruments has revealed a buffer amplifier developed especially for oscilloscope ...

A unique design flexibility that can either extend the maximum operating frequency of a power amplifier or allow the use of larger active devices with higher power handling capability. This paper ...

Linear Tech is aiming at high-impedance sensor transimpedance amplifiers with an op-amp that requires only 3fA of bias current (typical at 25°C) while offering 500MHz gain bandwidth product. Potential ...

As electronics rely more and more on ICs, subtle details about discrete components get lost because we spend less time designing with them. For example, a relay seems like a simple component, but ...
