Lecture #11 Feedback Circuits Instructor: Dr. Ahmad El-Banna December 2014
J-601-1448 Electronic Principals Integrated Technical Education Cluster At AlAmeeria © Ahmad El-Banna
Agenda 2 J-601-1448 , Lec#11 , Dec 2014 © Ahmad
El-Banna Feedback Concepts Feedback Connection Types Practical Feedback Circuits
Simple block diagram of feedback amplifier 3 J-601-1448 , Lec#11
, Dec 2014 © Ahmad El-Banna Some improvements are : 1. Higher input impedance. 2. Better stabilized voltage gain. 3. Improved frequency response. 4. Lower output impedance. 5. Reduced noise. 6. More linear operation.
FEEDBACK CONNECTION TYPES 4 J-601-1448 , Lec#11 , Dec 2014
© Ahmad El-Banna • Series feedback connections tend to increase the input resistance, whereas shunt feed-back connections tend to decrease the input resistance. • Voltage feedback tends to decrease the output impedance, whereas current feedback tends to increase the output impedance.
