CHAPTER 2
Linear Circuits – Part I
Operational amplifier circuits are used in almost all modern communication, instrumentation and computation systems. The output of an amplifier is proportional to input and the proportional constant is called the gain. An IC op-amp is made up of a large no of transistors, resistors and the capacitor connected in a complex circuit. In this chapter, we will discuss how operational amplifiers are used for buffers, inverting amplifiers, non-inverting amplifiers, inverting adders, non-inverting adders, differential amplifiers, instrumentation amplifiers, V/I converters, I/V converters, integrators, differential integrators and differentiators. Many linear and non-linear analog systems are constructed with op-amp ...
