Kusankha ndi Kugwiritsa Ntchito

Kusankha ndi kugwiritsa ntchito amplifiers.
Pali magulu ndi mitundu yambiri yama amplifiers ophatikizika, omwe ayenera kusankhidwa moyenera ndikugwiritsidwa ntchito molingana ndi zofunikira zenizeni zogwiritsira ntchito.
(1) Yesani kugwiritsa ntchito amplifiers ophatikizika ndi cholinga chonse.Makina akamagwiritsa ntchito ma amplifiers angapo, momwe angathere kuti agwiritse ntchito mabwalo angapo ophatikizika amplifier, monga LM324, LF347, ndi zina zambiri.
(2) Kusankha kwenikweni kwa Integrated ntchito amplifier, komanso kuganizira chikhalidwe cha gwero chizindikiro (ndi gwero voteji kapena gwero panopa), chikhalidwe cha katundu, Integrated ntchito amplifier linanena bungwe voteji ndi panopa kukwaniritsa zofunika, chilengedwe. zinthu, Integrated ntchito amplifier amaloledwa kugwira ntchito osiyanasiyana, voteji osiyanasiyana, mphamvu mphamvu ndi voliyumu ndi zinthu zina kukwaniritsa zofunika.Mwachitsanzo, pakukulitsa ma siginecha a AC monga ma audio ndi makanema, ndikofunikira kusankha amplifier yogwira ntchito yokhala ndi kutembenuka kwakukulu;pokonza ma siginecha ofooka a DC, ndi koyenera kusankha chokulitsa cholondola kwambiri (mwachitsanzo, detuning current, detuning voltage, and temperature drift are ang'ono).
(3) Musanagwiritse ntchito, ndikofunikira kumvetsetsa magawo ndi magawo amagetsi ophatikizira amplifiers ophatikizika, ndikuwunikira mawonekedwe a phukusi, makonzedwe otsogolera akunja, ma waya a pini, voteji yamagetsi, etc.
(4) Netiweki ya de-vibration iyenera kulumikizidwa momwe ikufunikira, poganizira kuchuluka kwa bandwidth pamalingaliro otha kugwedezeka.
(5) The Integrated Operation Amplifier ndiye maziko a dera lamagetsi, kuti achepetse kuwonongeka, njira zotetezera ziyenera kuchitidwa.

Zizindikiro ndi Malangizo

Zizindikiro zogwiritsira ntchito amplifier ndi malangizo opangira ntchito
M'zochita, amplifiers ambiri-cholinga ntchito ayenera kugwiritsidwa ntchito mmene ndingathere, chifukwa n'zosavuta kupeza ndi okwera mtengo, kokha pamene ambiri-cholinga mtundu sangathe kukwaniritsa zofunika, angagwiritse ntchito mtundu wapadera, amene angathe kuchepetsa ndalama, komanso zosavuta kuonetsetsa kotunga.
Ndi chitukuko cha teknoloji yokhwima, kugwiritsa ntchito ma amplifiers akuchulukirachulukira, ndipo pamaso pa mitundu yosiyanasiyana ya ma amplifiers ogwirira ntchito, pali malangizo ena omwe amagwiritsidwa ntchito posankha.Izi ndi kusankha kukwaniritsa zofunika, komanso kupulumutsa deta magwero ankasewera kwambiri.Zizindikiro zosankhidwa zomwe zimagwiritsidwa ntchito kwambiri ndi:
Gawo loyamba ndikusankha voteji.Monga ma amplifiers ambiri omwe amapangidwa kuti azigwiritsidwa ntchito m'mafakitale ndi ± 15V, koma poganizira kuti akuyenera kupangidwira zida zam'manja zomwe zimagwira ntchito pa 3V (kapena pansi pa 5V), mndandanda wa ± 15V ukhoza kuchotsedwa.Kuphatikiza apo, chigamulo chomwe phukusi ndi mtengo ziyenera kukhazikitsidwa pazofunikira.
Kulondola Kwambiri Kumagwirizana ndi kusiyanasiyana kwa voliyumu yolowera (Vos) ndi kusuntha kwake kwa kutentha komanso PSRR ndi CMRR.
Gain Bandwidth Product (GBW) The gain bandwidth ya mtundu wa voliyumu ya feedback gain op-amp imatsimikizira bandwidth yofunikira mu pulogalamu yomwe mwapatsidwa.
Kugwiritsa ntchito mphamvu (zofunikira za LQ) Nkhani yofunikira pamapulogalamu ambiri.Popeza ma amplifiers ogwirira ntchito amatha kukhala ndi vuto lalikulu pakugawa mphamvu kwa dongosolo lonse, quiescent current ndiyofunikanso kuganizira kamangidwe kake, makamaka pakugwiritsa ntchito batire.
Input bias current (LB) imatha kutengera komwe kumachokera kapena kusokoneza mayankho ndipo kumatha kubweretsa zolakwika.Mapulogalamu okhala ndi magwero apamwamba kwambiri kapena mayankho okwera kwambiri (monga ma transimpedance amplifiers kapena ophatikizira) nthawi zambiri amafuna mafunde ocheperako;Zolowetsa za FET ndi CMOS op amps nthawi zambiri zimapereka mafunde otsika kwambiri.
Kukula kwa phukusi kumadalira kugwiritsa ntchito ndipo op-amp imasankhidwa kuti igwirizane ndi zofunikira za phukusi.

Ubwino wake

Ubwino wa general op amps
Ubwino waukulu ndi mtengo wotsika, zomveka zolimbitsa thupi komanso zosankha zambiri zamalonda.

Mapulogalamu

Kugwiritsa ntchito ma op amps
Chifukwa cha mawonekedwe awo, amagwiritsidwa ntchito m'njira zosiyanasiyana.Ntchito zazikuluzikulu ndizo zomwe zofunikira zaumisiri zimakhala zochepa.Kukwaniritsa zosowa za ntchito, chuma ndi zothandiza zimapambana.Zolinga zophatikizika za ma Op amps ndizoyenera kukulitsa ma siginecha otsika.
