Amplifier biasing#
Introduction to biasing#
Principle of amplification
Amplifiers can be constructed with devices of which the voltage-to-current transfer of the output port depend on their operating point.
Presentation
The presentation Principle of amplification shows the way in which a basic amplifier stage can be constructed with a "transresistance" device.

Introduction to amplifier biasing
Biasing is the application of a collection of techniques for fixing the electrical operating conditions of electronic devices, and deriving the required bias voltage and current sources from the power supply source(s).
Presentation
The presentation "Principle of biasing" shows the way in which bias sources fix the devices' operating point, independent of the (passive) DC termination at the input port and the output port of the amplifier.

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.
