Unformatted text preview: 1 Operational Amplifiers ( “ Op Amp ” ) • V (I) controlled V (I) source – Active or passive element ? • Perform math “operations” – Addition – Subtraction – Multiplication – Division – Integration 1 BME 311 Network Theory John X.J. Zhang, UT Austin Integration – Differentiation Key Points of Chap. 5 • Ideal Op Amp • Op Amp math “operations” – Inverting Amp – Non-inverting Amp – Summing Amp – Difference Amp – Cascaded Op Amp 2 BME 311 Network Theory John X.J. Zhang, UT Austin – Cascaded Op Amp 2 Op Amp: Circuit Symbol 3 BME 311 Network Theory John X.J. Zhang, UT Austin 8-pin DIP: D ual I n-line P ackage Can we apply KCL… on Op-Amp ? Inside of an “Op-Amp” 4 BME 311 Network Theory John X.J. Zhang, UT Austin 3 Op Amp “Non-ideal” Equivalent Circuit v d =v 2-v 1 R i : input Thevenin equivalent resistance (ideal value=?) R o : output Thevenin equivalent resistance (ideal value=?) v =Av d =A(v 2-v 1 ) 5 BME 311 Network Theory John X.J. Zhang, UT Austin o A : open-loop voltage gain (ideal value=?) unit: dB=20 log 10 (A) Is Op Amp a liner system ?...
