Transimpedance amplifiers (TIAs) convert a current to a voltage. In many systems, this current comes from a photodiode. In order to test a TIA, it is best to drive the TIA with a current that emulates ...
This Idea For Design shows how a gyrator circuit can be used to perform certain ac tests on units under test that require a dc-current feed. Designers have long used the gyrator circuit to create a ...
