Litšobotsi tsa Sehlahisoa

Ketane ea matšoao le taolo ea matla: mefuta e 'meli ea bohlokoa ea chip ea analog

Lihlahisoa tsa ketane ea matšoao, tseo haholo-holo li nang le li-amplifiers tse sebetsang le li-converter tsa data, li sebetsana le litlhoko tsa tšebelisano ea tlhahisoleseding.Ka mokhoa o tsoakiloeng oa digital-to-analog, mokhoa o feletseng oa ts'ebetso ea pontšo ke o latelang.

Li-sensor: Lipontšo tsa 'mele tse tala tse tsoang lefats'eng le kantle, hangata molumo, litšoantšo, mocheso, mongobo, khatello, joalo-joalo, li nkuoa ke li-sensor mme li fetoleloa ho ba mats'oao a analoge a nako e tsoelang pele a tsamaellanang le mats'oao ana a 'mele, hangata ka sebopeho sa voltage/ jwale.

Li-amplifiers le li-filters: Lipontšo tsa analog li sebetsoa ke likarolo tsa boemo ba matšoao tse nang le li-amplifiers le li-filters.Amplifier e sebeletsa ho holisa mats'oao a manyane, a fokolang a analog ho a ikamahanya le mefuta e felletseng ea tlhahiso ea ADC;filthara e sebetsa haholo ho fokotsa lets'oao ho khotsofatsa litlhoko tsa theorem ea sampuli ea Nyquist.

Mofetoleli oa data: ADC e fetolela lets'oao la motlakase / lets'oao la hajoale hore e be bongata bo lumellanang ba dijithale, bo fuoang yuniti e latelang ea dijithale bakeng sa ts'ebetso.

Ts'ebetso ea dijithale: Lipalo tse felletseng tsa dijithale li tsamaisoa ke sistimi ea ts'ebetso ea dijithale (MCU, DSP, kapa FPGA), eo hangata e sebelisetsoang ho kenya tšebetsong li-algorithms tsa ts'ebetso ea mats'oao a dijithale.

Mofetoleli oa data: Lipalo tsa discrete tsa dijithale kamora ho sebetsoa ke sistimi ea ts'ebetso ea dijithale li romelloa ho DAC, eo ka eona li fetoloang ho ba lets'oao le tsoelang pele la analog.

Li-filters: Ha lets'oao la DAC le na le likarolo tsa "mohato" oa maqhubu a phahameng, sefahla sa reconfiguration se sebelisoa ho sefa lerata le phahameng haholo, se hlahisang lets'oao la tlhahiso ea analog e hlophisitsoeng bocha.

Ntho ea bohlokoa ka ho fetisisa ho tsena ke amplifier ea ts'ebetso le converter ea data.

Li-amplifiers tse sebetsang ke "mehaho ea motheo" ea li-circuits tsa analog 'me li sebelisoa mefuteng e mengata ea likopo.Li-amplifiers tse sebetsang ke li-circuits tse holisang tse eketsang le ho kopanya matšoao a analoge 'me hangata li sebelisoa ho holisa matšoao a manyane, a fokolang ho a maholo.Ka nako e ts'oanang, li-amplifiers tse sebetsang ke motheo oa lisebelisoa tse ngata tsa analog, tse kang li-converter tsa digital-to-analog, li-converter tsa hona joale ho ea ho motlakase, li-filters, li-comparators le li-linear regulators.Ho ka boleloa hore li-amplifiers tse sebetsang ke "mehaho ea motheo" ea lipotoloho tsa analog.

Li-converter tsa data ke borokho lipakeng tsa litsamaiso tsa analog le tsa dijithale mme li bohlokoa.Sefetoleli sa analog-to-digital (ADC) se na le boikarabelo ba ho fetola matshwao a analoge hore e be matshwao a dijithale mme converter ya dijithale ho ya ho analoge (DAC) e na le boikarabelo ba ho fetolela matshwao a dijithale hore e be matshwao a analoge.Li-sensor li fetolela mocheso oa lefatše oa 'nete, likhatello, melumo, joalo-joalo hore e be mats'oao a motlakase, ao hangata e leng matšoao a analoge 'me a ke keng a lemohuoa le ho sebetsoa ke litsamaiso tsa dijithale.Ke feela ka ho sokoloha ke ADC moo ba ka tšoaroang le ho sebetsoa ke MCU.Ho feta moo, libui, joalo-joalo, li hloka ho kenya lets'oao la analog hore li sebetse, kahoo ho hlokahala li-DAC ho fetolela tlhahiso ea matshwao a dijithale ka sistimi ea dijithale hore e be matšoao a analoge.Ka hona, neng kapa neng ha ts'ebetso ea dijithale e ameha, mofetoleli oa data o tlameha ho ba teng.

Op-amps ke motheo oa lisebelisoa tse ngata tsa analog, mohlala, li-filters li entsoe ka op-amps le resistors.

Li-converter tsa data li kenyelletsa li-converter tsa digital-to-analog (DACs) le li-analog-to-digital converters (ADCs)

Tsamaiso ea matla ke ntho e hlokahalang bakeng sa lipotoloho tsa elektroniki.Hafeela tsamaiso ea elektronike e hloka phepelo ea motlakase, lisebelisoa tse tloaelehileng tsa matla ke li-adapter tsa matla, libeteri, joalo-joalo Ho itšetlehile ka mofuta oa ho kenya le ho hlahisa hona joale, re ka arola batsamaisi ba matla ka mefuta e 4 e meholo: AC-DC (rectifier), AC. -AC (inverter, joalo-joalo), DC-DC (chopper), le DC-AC (inverter).

Switching rectifiers (AC-DC) ke eona e ikarabellang haholo bakeng sa ho fetola matla a AC hore e be matla a DC 'me hangata a fumanoa ho li-adapter tsa motlakase bakeng sa lilaptop.

Li-converter tsa AC-AC (AC-AC) li na le boikarabello ba ho fetolela maqhubu a itseng a matla a AC ho a mang a sa fetoheng kapa a feto-fetohang a matla a AC.

Motlakase oa DC-DC (DC-DC) o fetola matla a DC hore e be matla a mang a DC a nang le litšobotsi tse fapaneng tsa maqhubu, mohato, hona joale le motlakase.

Li-inverters (DC-AC) li-switch converter tse fetolelang matla a DC hore e be matla a AC, tse ling li li bitsa li-converter, 'me ke likarolo tse ka sehloohong tsa phepelo ea motlakase ea AC le lisebelisoa tsa motlakase tse sa senyeheng (UPS).

Li-chips tsa taolo ea matla ke li-circuits tsa taolo ea matla tse kopaneng tseo mesebetsi ea tsona e ka sehloohong e leng taolo ea motlakase, matla a matla a motlakase, motlakase o sa feleng, phetoho ea AC-DC, joalo-joalo. Li arotsoe ka li-linear voltage regulator (LDO), li-charge-pump (Charger-pump), DC. -DC converters (DC-DC), AC-DC converters (AC-DC), LED driver chips, joalo-joalo Lisebelisoa tse tloaelehileng ke li-charger le li-driver tsa LED bakeng sa lisebelisoa tsa elektronike tsa bareki tse kang liselefouno le lik'homphieutha tsa libuka.Mohlala, lilaoli tsa motlakase li theola motlakase o moholo oa 220V ebe li ntša motlakase o tlase oa DC o tsitsitseng hore o sebelisoe lik'homphieutheng tsa libuka;Bakhanni ba LED ba phahamisa matla a ka hare a liselefouno ho khanna mahlaseli a lik'hamera.
