Amplifier The amplifier invented during the second world war its was work to do

Amplifier The amplifier invented during the second world war its was work to do mathematical operations that time that why named operation amplifier. The modern amplifier different from the former in the way of making its , small size and its performance outstanding.

Amplifier Is the circle electronic you repeat the signal input , we will have

Amplifier Is the circle electronic you repeat the signal input , we will have signal similar to the reference within but doubles its value It have one output and two input the first celled inverter and the other celled non inverter

 Amplifier is integration circuit contains on a many of transistors , resistors and

Amplifier is integration circuit contains on a many of transistors , resistors and capacitors integrated into a single chip.

Property of operation amplifier Common-mode gain: Acm<1 Common –mode rejection ratio: CMRR=Aol/Acm Input bias

Property of operation amplifier Common-mode gain: Acm<1 Common –mode rejection ratio: CMRR=Aol/Acm Input bias current: IBAISE=I 1+I 2/2 Input offset current : Ios=|I 1 -I 2| The most type using operation amplifier ( 741)

 Offset voltage: Vos=Ios Rin Output error voltage : Vout(error)=Av. Ios. Rin Slaw rate

Offset voltage: Vos=Ios Rin Output error voltage : Vout(error)=Av. Ios. Rin Slaw rate : SR=∆Vout/∆t Power dissipation : P=Iout. Vd

Properties of amplifier Ø high voltage gain Ø Very high input impedance Ø Very

Properties of amplifier Ø high voltage gain Ø Very high input impedance Ø Very low output impedance Ø Wide bind width

Input single modes In this type of amplifier one of input tied with inverter.

Input single modes In this type of amplifier one of input tied with inverter. if the inverter tied with the negative terminal the amplifier making the signal inverted and large

Input single modes And if the inverter were tied with the positive term the

Input single modes And if the inverter were tied with the positive term the amplifier will magnify the signal just and will keep the province on its original form

Double ended differential In addition to using only one input , it is possible

Double ended differential In addition to using only one input , it is possible to apply signal at each input this being a double ended operation, us shown an input (Vd) applied between the two input terminal , with the resulting amplified output in phase with that applied between the plus and minus input us show the same action resulting when two separate signal are applied to the inputs , the difference signal being input
