Introduction l.jpg
Introduction

  • Amplifier is a device which senses an

    input and produces a larger version of it.

  • Amplifiers are used to boost electrical

    signals in devices (radio, televisions..)

  • Op-Amp: Class of High gain DC Amplifiers

    with two inputs and Single output

Inverting and non inverting l.jpg
Inverting and Non-Inverting

Inverting Amplifier:

  • Non- Inverting input is grounded.

  • Signal is applied to the Inverting input.

  • Output is 180o out of Phase.

Non inverting amplifier l.jpg
Non-Inverting Amplifier

  • Inverting input is grounded.

  • Signal is applied to the Non-Inverting input.

  • Output is in Phase.


Closed loop connection l.jpg
Closed Loop Connection

  • “Output is applied back in to the Inverting Input.”

  • Used in both Inverting and Non-inverting modes of Operation.

What is gain l.jpg
What is Gain??

Gain = Output / Input

Gain of Op-Amp (Inverting Mode)=-Rf/R1

Gain of Op-Amp (Non-inverting Mode)=1+Rf/R1




Differential and common mode l.jpg
Differential and Common mode

  • Common Mode: When both inputs of the signal have the same common voltage..

  • Output will be zero in the common mode.
