Posts tagged electronics-basic-building-block

4 child tags

This tag is an umbrella tag used as a parent for more specific tags that describe the basic building blocks used in electronic circuits.

This is not about "conceptual blocks", i.e. general block-diagram functions (e.g. oscillator, differential amplifier, etc.), but about practical circuit configurations like "differential pair", "Darlington configuration", "push-pull stage", etc.

This tag doesn't have a detailed wiki yet.

Q&A Design considerations for a differential pair

Differential pairs, such as for ethernet or a CAN bus, can be designed to be loosely coupled or tightly coupled. For a loosely coupled differential pair, the odd-mode and even-mode impedances are ...
