Calculating the feedback factor for an op amp that is set up for current-to-voltage conversion may be a bit of a mystery to many engineers. By deriving the transfer function for a transimpedance ...

Transimpedance amplifiers (TIAs) form the essential front end of optical receivers, converting the minute current produced by a photodiode into a usable voltage signal. Design of TIAs for modern ...

Looking at the amplifier circuit shown in Figure 1, one could estimate how stable it is by determining the phase shift encountered when the signal goes around the loop one time, while the loop is ...

For Part 1, click here. High-speed optical communications applications have some high-level transimpedance-amplifier (TIA) circuit similarities with laser rangefinders (LRFs) and LiDAR. However, there ...

A fundamental difficulty of working with nanoparticles is that your objects of study are too small for an optical microscope to resolve, and thus measuring their size can be quite a challenge. Of ...

In a simplified schematic from its datasheet, Linear Technology's LTC6268 (and 6269 dual) provide no evidence of "secret sauce." Rather, it shows a combination of semiconductor design and process ...
