Meta Description
Ngatidzidze mutsauko uripo pakati peVCC, VEE, VDD, neVSS sekushandiswa kwemagetsi. Tichaongorora tsananguro dzadzo, dhizaini dhizaini, uye inoshanda mashandisiro muICs, amplifiers, uye microcontrollers.
ziviso
Masisitimu emazuva ano emagetsi haagone kuve nehupenyu kana tikaisa parutivi tekinoroji yekugovera magetsi. Iyo magetsi ndiyo musana wemagetsi ese emagetsi. Kunzwisisa mazwi anoshandiswa mumagetsi anoumba hwaro hwekugadzira mapurojekiti anoshanda.
Matemu akaita seVCC, VEE, VDD, uye VSS akajairwa mumadhairekita emagetsi, zvinyorwa zvedhizaini, uye zvirongwa, uye vagadziri uye mainjiniya vanofanirwa kuwana pfungwa dzese zvakanaka. Aya ndiwo magadzirirwo emazita emagetsi uye akakosha mukuita kuti zvive nyore kunzwisisa magetsi emagetsi uye mapini anowanikwa muzvikamu zvemagetsi senge ICs, amplifiers, uye mamwe maseketi anoshanda.
Ichi chinyorwa chinopa gwara rakazara kumatemu aya, zvazvinoreva, uye mabasa awo mudunhu. Neruzivo rwakadaro, unogona kuvandudza dunhu rako mashandiro uye kugona kuchengetedza yakakwirira chiratidzo chekuvimbika zviyero.
Tsanangudzo dzeVCC, VEE, VDD, uye VSS
VCC
VCC chidimbu chevoltage pane common collector. Izvi zvinoreva simba rakanaka rekupa mune yemagetsi dunhu uchishandisa BJT. Maseketi akadai ane mapini ekuunganidzira etransistor akabatana nemagetsi emagetsi emagetsi sosi, nokudaro achiwana zita rekuti common collector. Mienzaniso yenzvimbo dzekushandisa dzinosanganisira +5V muTTL logic maseketi.
VEE
VEE ndiyo Yakajairwa Emitter voltage, iyo inoreva iyo yakaipa voltage inopihwa mumaseketi eBJT. Iyo emitter ndiyo inogadziriswa inowanzoitika kune BJT transistors; saka, ndiyo inowanzo emitter. Kuti uwane kunzwisisa kuri nani kweVEE, ona Mufananidzo 1 pamusoro.
VDD
VDD inomiririra ye transistor's drain voltage. Izwi iri rinoshandiswa mundima effect transistors. Kunyanya, yakajairika mune metol-oxide semiconductor FETs. Iyi ndiyo FETs positive power supply, iyo inobatanidza transistors drain terminal.
ndima
VSS ndiyo voltage kunobva maFET transistors. Inomiririra iyo yakaipa kana yepasi voltage muFET transistor maseketi. Mune MOSFET, iyo sosi terminal ndiyo inotaridza nzvimbo yemagetsi ese ari mukati medunhu iroro. Kuti unzwisise zvakawanda nezveVSS, ona Mufananidzo 2 pamusoro.
Circuit Applications yeVCC, VEE, VDD, uye VSS
BJT Circuits
Mumaseketi eBJT:
- VCC inoshandiswa kusimbisa iyo transistor muunganidzi terminal, nekudaro ichigonesa dunhu kuti riwane kukwidziridzwa uye kushandura mashandiro.
- VEE inoita kuti BJT ive neyakafanana pane emitter terminal.
FET Circuits
Kana zvasvika kune maFET:
- VDD inoshandiswa kusimbisa iyo transistor drain, nokudaro ichibvumira iyo transistor kudzora ikozvino.
- VSS ndiyo yakaipa voltage referensi ye transistor source terminal.
Kukosha Kwechiratidzo Kutendeseka
Iwe unofanirwa kugovera nenzira kwayo VCC, VEE, VDD, uye VSS kuchengetedza yakanyanya kunaka chiratidzo. Iyo voltage referensi inodzikamisa yedunhu voltage uye inosefa ruzha, nekudaro ichipa dunhu uye zvikamu zvakaringana kuita.
Tafura 1 : Pfupiso Tafura yeSignals dzeSimba
| Kusarudzwa | Transistor Rudzi | Typical Chinangwa |
| VCC | BJT | Positive supply voltage |
| VEE | BJT | Negative reference voltage |

Kukosha Kweaya Matemu muSeti Dhizaini
Sei Kuisa Mazita Kunokosha
Kunyora chaiko kweVCC, VSS, VDD, uye VEE mune zvigadzirwa zvako, schematics, uye mamwe magwaro anovimbisa kududzira kwakaringana data data. Kurongeka uku kunovimbisa kuti ma voltages ako anodudzirwa zvakakwana uye mapinoti chaiwo anopihwa.
Kana iwe ukanyora zvisirizvo magetsi ako emagetsi, zvinotevera zvinonetsa zvinotarisirwa:
- Kukuvadzwa kwechikamu: Overvoltage inogona kuitika kana ukadudzira zvisizvo yako voltage pinout. Iyi overvoltage inogona kuparadza zvinhu zvinonzwisisika senge transistors, amplifiers, uye ICs.
- Kusagadzikana uye ruzha: Paunopa ma voltages ako zvisina kunaka, tarisira kuwedzera ruzha, izvo zvinogona kuita kuti dunhu rako risagadzikana uye kukanganisa kushanda.
- Kusashanda zvakanaka kwedunhu: Kukanganisa kwemagetsi pinout kunogona kukonzera kutadza kwedunhu uye humwe hunhu husina kunaka.
Ndeapi maVoltage Standards Mhiri kweIC Mhuri
Mhuri dzakasiyana dzeIC dziripo munzvimbo yese yemagetsi. Idzi mhuri dzeIC Dzine magungano akasiyana emagetsi:
- Transistor-Transistor Logic (TTL): Inoshandisa iyo VCC kune yakanaka voltage uye VEE yepasi.
- Complementary Meta-Oxide Semiconductors (CMOS) Izvi zvinoshandisa VDD kune yakanaka voltage uye VSS yepasi.
- Operational Amplifiers: Iyi inoshandisa VCC uye VEE kune dua yekugovera masisitimu.
Kushanda Kushanda Kweaya Matemu mune Yemazuva Ano Electronics
Aya mazwi akakosha mune microcontrollers, mashandiro amplifiers, akamisikidzwa masisitimu, uye odhiyo amplifiers.
Microcontroller
Microcontrollers senge ARM uye AVR mhuri dzinoshandisa iyo VDD neVSS yekusimbisa. Yakakodzera VSS uye VDD yekubatanidza inoita kuti iyo microcontroller ishande nemazvo nemidziyo yeperipheral senge actuators uye sensors.
Mufananidzo 3 : Microcontroller
Operational Amplifier
Iyo mbiri mbiri yekugovera dhizaini yeanoshanda amplifiers, VCC uye VEE, yakanakisa kufunga, iyo inopa dhizaini yako yakanaka uye isina kunaka terminal. Iyo gadziriso inobatsira mukuisa chiratidzo uye kugadzirisa odhiyo.
Audio Amplifiers
Iine chaiyo VCC uye VEE, magetsi amplifiers anogona kukwidziridza masaini masaini neakanakisa kusefa kweruzha uye kudzivirira kukanganisa. Nesimba chairo rinopihwa, ruzha rwakarurama rwunowanikwa.
Matambudziko uye Mafungiro Paunenge Uchishandisa Aya Matemu
- Zvakajairwa Pitfalls Dziviriro: Paunenge uchiita zvikanganiso uchinyora ma voltages tarisira nyaya dzakadai seyakatarisana nemagetsi madomasi, izvo zvinokonzeresa kusawirirana, zvakanyanya kana VDD neVCC zvachinjana. Imwe nyaya inogona kuitika ndeye pasi loop, iyo inotangira kubva kune isina kufanira grounding. Izvi zvinokonzera kukanganisa uye ruzha, zvichikanganisa kutendeseka kwechiratidzo.
- Kuve nechokwadi kuenderana: Kana dhizaini yako ikanamatira kune yakajairwa voltage referensi, iwe unobatanidza zvisingaite mamodule ako uye zvikamu. Injiniya inonzwika uye mugadziri anofanirwa kusimbisa kuti mazinga emagetsi anosangana nezvinodiwa zvekushanda uye anoenderana nemagadzirirwo awo.
mhedziso
Kuziva iyo VCC, VEE, VDD, uye VSS ndeyekuwedzera kune ese mainjiniya nevagadziri munzvimbo yemagetsi dhizaini. Matemu anovimbisa kuti iwe unoshandisa uye unonongedza ma voltages ako zviri nyore. Ivo zvakare vanobatsira kusimbisa kuti maBJT ako nemaFET ari kushanda nemazvo. Neruzivo rwakanyanya rwemazwi aya, unokwanisa kudzivirira zvikanganiso zvinogara zvichiitika, kuvandudza kutendeseka kwechiratidzo, uye kugadzira maseketi akasimba.
Neruzivo rwakakodzera nezveVCC, VEE, VDD, uye VSS, unogona kuve mugadziri akanaka ane hunyanzvi hunodiwa mukugadzirisa matambudziko uye kugadzirisa dunhu. Iwe hauzopikiswe kushanda nemaseketi akadai semamicrocontrollers, akamisikidzwa masisitimu, uye anoshanda amplifiers.
