Introduction to biasing#

Biasing of operational amplifiers

Operational amplifiers are commonly used as controllers in feedback circuits. In order to operate, they should be biased properly.

Presentation

The presentation "Biasing of operational amplifiers" shows the biasing quantities that should establish the proper operating conditions for operational amplifiers.
