Current Series Feedback Amplifier Examples. Solution 1 topology identification. The non inverting amplifier an example of series shunt feedback the op amp acts like a voltage amplifier the feedback network samples the output voltage voltage divides it and feeds back a voltage into the input so that v in is the sum of input and fed back v.
This application note will answer some questions and give a jumpstart to apprehensive designers. 19 3 shows this adjustment added to a noninverting circuit. The feedback network shares with the op amp think a finite input impedance.
Series shunt example 3 a series shunt feedback bjt amplifier is shown in fig.
Fet common drain amplifier source follower i. Two examples of the voltage series topology are considered in this section i. The common emitter or source amplifier may be viewed as a transconductance amplifier i e. The current feedback operational amplifier cfoa or cfa is a type of electronic amplifier whose inverting input is sensitive to current rather than to voltage as in a conventional voltage feedback operational amplifier vfa.
