Ho utloisisa Lipotoloho tsa Amplifier: Tlhaloso e Felletseng

Li-amplifiers tsa elektroniki kapa tsa motlakase ke lipotoloho tse sebelisang matla a kantle ho hlahisa mats'oao a tlhahiso ao e leng likopi tse kholoanyane tsa matšoao a kenyellelitsoeng. Tšebeliso e 'ngoe e tloaelehileng ea li-amplifiers ke lits'ebetsong tsa molumo, moo li sebelisetsoang ho eketsa molumo oa libui ho etsa hore molumo o utloahale libakeng tse kholo. Le ha voltage e le lets'oao le atileng haholo la ho kenya li-amplifiers, li-amplifiers tse ling li etselitsoe ho eketsa hona joale. Li-amplifiers tse eketsang lebelo la hona joale la tlhahiso li tsejoa e le li-amplifiers tsa matla.

Boholo ba li-amplifier li etsa li-linear amplification, empa tse ling ka tlhaho ke logarithmic. Litšoantšong tsa potoloho, li-amplifiers hangata li emeloa ke kgutlotharo. Ha re hlahlobeng moelelo oa li-diagram tsa potoloho ea amplifier mme re hlahlobe mefuta ea tsona.

Litšoantšo tsa potoloho ea Amplifier li Bolela'ng?

Litšoantšo tsa potoloho ea amplifier li emela sebopeho le likhokahano tsa likarolo tsa potoloho ea amplifier. Hangata li kenyelletsa transducer ea ho khetha, e fetolang lets'oao la 'mele hore e be lets'oao la motlakase. Joale letšoao lena la motlakase le matlafatsoa ke amplifier e nyenyane ea pontšo, e eketsa matla a eona.

Ka mor'a ho matlafatsa, lets'oao le romelloa ho transducer ea tlhahiso, e fetolang letšoao la motlakase hore e be letšoao la 'mele. Qetellong, sebuela-hōle se seholo se phahamisa lets'oao ho fihla boemong bo loketseng bakeng sa ho khanna mojaro, joalo ka sebuela-pele kapa enjene.

Litšoantšo tsa potoloho ea amplifier li arotsoe ka mefuta e 'meli ea mantlha: li-circuits tsa amplifier tsa matla le li-circuits tsa amplifier tsa voltage. Li-circuits tsa amplifier tsa motlakase li etselitsoe ho eketsa boemo ba matla a lets'oao, ha li-circuits tsa amplifier tsa voltage li tsepamisitse maikutlo ho eketsa boemo ba motlakase. Mefuta ena e 'meli ea li-amplifiers e sebeletsa merero e fapaneng mme e na le lintlha tse fapaneng tsa moralo.

Potoloho ea Voltage Amplifier

Sepheo se seholo sa potoloho ea amplifier ea voltage ke ho nyolla boemo ba motlakase oa lets'oao. Mofuta ona oa potoloho o etselitsoe ka ho khetheha ho fumana phaello e ngata ha o ntse o hula matla a fokolang ho tsoa tlhahiso. Ho fihlela amplifier e phahameng, litekanyetso tse itseng li tlameha ho finyelloa ke li-circuits tsa amplifier tsa voltage:

1. Khetho ea Transducer: Transducer e sebelisoang potolohong e lokela ho ba le motheo o mosesaane, ka tloaelo o sebelisa li-beta / li-transistors tse phahameng tse nang le boleng bo boholo ho feta 100. Sena se tiisa hore ho matlafatsa matšoao a sebetsang hantle.
2. Tšebelisano ea Impedance: The impedance ea potoloho e lokela ho ba e batlang e le tlaase ho bapisoa le impedance e hlahisoang. Sena se lumella phetiso ea mats'oao e sebetsang ntle le tahlehelo ea motlakase.
3. Ts'ebetso e tlase ea hajoale: Amplifier ea motlakase e lokela ho sebetsa ka nako e tlase, hangata e haufi le 1mA. Sena se nolofalletsa potoloho ho sebetsana le meroalo e phahameng ea pokello, e leng ea bohlokoa bakeng sa ho fumana phaello e phahameng ea motlakase.
4. RC Coupling: RC coupling ke mokhoa o tloaelehileng o sebelisoang ho hokahanya mekhahlelo e fapaneng ea potoloho ea amplifier ea voltage. Mokhoa ona oa ho kopanya o khethoa ka lebaka la ts'ebetso ea eona ea litšenyehelo le boiketlo ba ho kenya ts'ebetsong, ho netefatsa hore ho fetisoa ha matšoao a boreleli pakeng tsa mekhahlelo.

Ka ho latela litlhokahalo tsena, li-circuits tsa amplifier tsa voltage li ka nyolla boemo ba motlakase oa lets'oao, tsa li etsa tse loketseng lits'ebetso tse fapaneng tsa elektroniki.
