Amfutar da Inverting Operational Amplifier | Inverting Op Amp
Mai suna inverting amplifier?
Inverting amplifier (ko da ake kiran inverting operational amplifier ko inverting op-amp) shine ɗaya daga cikin operational amplifier na ke gina aiki mai samar da output wanda ya fi shiga 180o da input.
Wannan yana nufin cewa idan pulse na input ce mafi yawan mutane, akwai za a iya samun pulse na output mafi yawan hasken mutane, kuma vice versa. Tabbacin da aka bayar tana nuna inverting operational amplifier da ake gina ta saboda amfani da op-amp da biyu resistors.
A nan ne ake amfani da signal na input zuwa terminal na inverting ta op-amp saboda resistor Ri. A nan ne ake saka terminal na non-inverting zuwa ground. Mafita haka, a nan ne ake bayar feedback na zama don tabbatar da circuit, kuma don kontrol output, saboda feedback resistor Rf.
Daga matsayin lissafi, voltage gain na circuit shine 
Amsa,
Amma, a nan ne a sanu cewa ideal op amp na input impedance da ba ta ba, saboda haka, currents na input terminals su zero i.e. I1 = I2 = 0. Saboda haka, Ii = If. Haka, 
A nan ne a sanu cewa a ideal op amp, voltage na inverting da non-inverting inputs su daidai.
Saboda a nan ne ake saka non-inverting terminal zuwa ground, zero voltage na non – inverting terminal. Wannan yana nufin cewa V2 = 0. Saboda haka, V1 = 0, kuma. Don haka, za a iya rubuta 
Daga abubuwan lissafin, a nan ne ake samun 
Voltage gain na inverting operational amplifier ko inverting op amp shine 
Wannan yana nufin cewa voltage gain na inverting amplifier an tabbata a kan ratio na feedback resistor zuwa input resistor, kuma minus sign yana nuna phase-reversal. Kuma, a nan ne a sanu cewa input impedance na inverting amplifier shine Ri.
Inverting amplifiers suna da linear characteristics masu kyau wanda ke taimakawa a yi DC amplifiers. Amma, ake amfani da su don haɓaka input current zuwa output voltage a form of Transresistance ko Transimpedance Amplifiers. Kuma, ake amfani da su a audio mixers a form of Summing Amplifiers.
