Operational Amplifier na nufin wani babban kogin da ake amfani da shi a cikin ilimin kula da taurari, wanda yake da kyakkyawan hankali da kula masu inganci.
Takaitaccen Op Amp
Op amp (operational amplifier) yana nufin kogin kashi da tashar karshe mai sauƙi da ake amfani da shi a cikin hanyoyi na elektroniki daban-daban.
Siffofinta
Op amp yana kawo tasirin bayanai biyu na mafi girman, wanda ake kira differential input voltage, a cikin siffofinta ta open loop.
Siffofinta Closed Loop
A cikin siffofinta closed loop, ana kara feedback don kontrola signalin mafi girma, ana yi positive feedback don oscillators kuma negative feedback don amplifiers.
Abubuwa na Op Amp
Voltage gain na tsawon (Don samun output mafi girma)
Input resistance na tsawon (Saboda haka zan iya kula da shi a kan sakamako)
Output resistance na ɗaya (Don haka ba za a gama output saboda canza load current ba)
Bandwidth na tsawon
Noise na ɗaya
Power supply rejection ratio (PSSR = 0)
Common mode rejection ratio (CMMR = ∞)
Amfani da Op Amp
Op amps su ne da kayayyakin da ake amfani da su a hanyoyi daban-daban, tare da amplifiers, buffers, summing circuits, differentiators, da integrators, saboda kyaukarsu da inganci.
