What is the input impedance of a transimpedance amplifier (TIA)? Infinite? Zero? No, what is it really? Nothing is really zero or infinite, right? The answer might surprise you—worth understanding, ...

When used with other blocks and modules, a new approach to modeling operational-amplifier output impedance behavior can provide a more realistic overall behavioral model. Simulating the behavior of a ...

As you probably know if you've been shopping for cables, coax for most video applications is "75 ohm" coax–but what the heck does that mean, anyway? This article is a short, non-technical explanation ...
