Chapter 14. Operational Amplifiers

Operational Amplifiers Integrated circuit, also known as op amp. Wide range of applications.  Ideal operational amplifier : - inverting and non-inverting input terminals. - common mode signal & differential mode signal - infinite input impedances - zero output impedance - very large open –loop gain.

14.2 Inverting amplifiers

Example 14.1 : Analysis of an inverting amplifier

Exercise 14-17

Exercise 14-18

Differentiator Circuit

Active Filters Produce bandpass and bandreject filters without using inductors. Inductors are usually large, heavy, costly and generate electromagnetic field. Fewer components Transfer function is insentitive to component tolerances. Allow a wide range of transfer functions. Inappropriate for monolithic fabrication.

Fig Filter Types. Fig Ideal transmission characteristics of the four major filter types : (a) low pass (LP), (b) high pass (HP), (c ) bandpass (BP) and (d) bandstop (BS).
