Linear Applications of Operational Amplifier

Objectives

Analysis and design concepts of some applications of operational amplifier:

  • Sign changer, scale changer, inverting, and non-inverting amplifier.
  • Integrator, differentiator, and its application in analog computer.
  • Current to voltage (C–V or C/V ) and voltage to frequency (V–F or V/F ) circuits.
  • Voltage to frequency (V–F or V/F ) and frequency to voltage (F–V or F/ V ) conversion circuits.
  • Different circuits using op amps are analysed with input and output signal waveforms.
3.1 INTRODUCTION

Conventional amplifiers are used to strengthen the amplitude of real time signals, without causing distortion in wave shape and frequency response, whereas operational amplifier IC finds many applications ...
