Analogue hloov
Covanalogue(los yogPETR)hloov, kuj hu uahloov ob sab, yog ibhluav taws xobtivthaiv uas coj zoo ib yam li arelay, tab sis tsis muajtxav qhov chaw.Qhov hloov pauv feem ntau yog ib khub ntawmMOSFET transistors, ib qho khoom siv N-channel, lwm yam khoom siv P-channel.Lub cuab yeej tuaj yeem ua cov cim analog lossis cov cim digital hauv ob qho kev taw qhia thaum qhib thiab cais cov hloov pauv hloov pauv thaum tawm.Analogue keyboards feem ntau yog tsim raws liintegrated circuitshauv cov pob khoom uas muaj ntau lub keyboards (feem ntau yog ob, plaub lossis yim).Cov no suav nrog 4016 thiab 4066 los ntawm4000 series.
Kev tswj cov tswv yim rau lub cuab yeej yuav yog lub teeb liab uas hloov ntawm qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob, nrog rau qhov zoo dua qhov hluav taws xob hloov lub cuab yeej rau thiab qhov tsis zoo hloov lub cuab yeej tawm.Lwm cov circuits yog tsim los sib txuas lus los ntawm qhov chaw nres nkoj serial nrog tus tswv tswj hwm txhawm rau teeb tsa cov keyboards rau lossis tawm.
Lub teeb liab raug hloov yuav tsum nyob hauv thaj tsam ntawm qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob uas txuas nrog P-MOS thiab N-MOS lub cev terminals.Qhov kev hloov feem ntau muab kev sib cais zoo ntawm cov teeb liab tswj thiab cov teeb liab tawm tswv yim / tawm.Lawv tsis siv rau high voltage switching.
Cov tsis tseem ceeb ntawm kev hloov pauv analogue yog:
- on-resistance: qhov tsis kam thaum hloov rau.Qhov no feem ntau yog los ntawm 5ohms uamus rau ob peb puas ohms.
- off-resistance: qhov tsis kam thaum hloov tawm.Qhov no feem ntau yog ntau megaohms lossis gigaohms.
- teeb liab ntau yam: qhov tsawg kawg nkaus thiab siab tshaj voltages tso cai rau lub teeb liab hla dhau.Yog tias cov no dhau lawm, qhov hloov pauv yuav raug rhuav tshem los ntawm cov dej ntws ntau dhau.Cov qub hom keyboards tuaj yeem ua tauluj up, uas txhais tau hais tias lawv txuas ntxiv ua cov dej ntws ntau dhau txawm tias tom qab lub teeb liab tsis raug tshem tawm.
- nqi txhaj tshuaj.Qhov kev cuam tshuam no ua rau qhov hloov mus txhaj me mehluav taws xobrau hauv lub teeb liab thaum nws switches rau, ua rau me mentsia hlau lojlos yogglitch.Tus nqi txhaj tshuaj yog teev nyob rau hauvcoulombs ua.
Analogue keyboards muaj nyob rau hauv ob qho tib sidhau-qhov technologylos yog los ntawmnto-mount technologypob khoom.
Ib qho kev hloov pauv analog yog qhov hloov pauv uas siv cov yam ntxwv ntawm JFET lossis MOS los tswj txoj kev teeb liab.
Ib qho analog hloov pauv yog qhov hloov pauv uas sivcov yam ntxwv ntawm JFETlos yogMOSlos tswj cov teeb liab txoj kev, thiab yog tsuas yog siv los ua kom tiav qhov kev hloov pauv ntawm cov teeb liab txuas txuas lossis kev sib txuas.Vim tias nws tsis siv hluav taws xob tsawg, ceev ceev, tsis muaj kev sib cuag nrog cov neeg kho tshuab, qhov loj me thiab lub neej ua haujlwm ntev, nws tau siv dav hauv ntau lub tshuab tswj tsis siv neeg thiab cov khoom siv hluav taws xob digital.
Cov qauv ntawm cov txheej txheem CMOS cov txheej txheem analog hloov tau pom nyob rau hauv daim duab 1. Kev sib txuas NMOS thiab PMOS nyob rau hauv parallel tso cai rau cov teeb liab hla kev sib npaug ntawm ob qho tib si.Lub rooj vag yog siv los tswj qhov tig-on thiab tig-tawm ntawm qhov hloov.NMOS tig rau thaum Vgs yog qhov zoo, thiab tua thaum Vgs tsis zoo, thiab PMOS ua qhov sib txawv.Vim muaj cov yam ntxwv sib txawv ntawm PMOS thiab NMOS, qhov hloov pauv ntawm lawv muaj cov yam ntxwv qhia hauv daim duab hauv qab no.Tus nqi ntawm cov teeb liab tam sim no nqa ntawm NMOS thiab PMOS yog txiav txim los ntawm qhov piv ntawm cov tswv yim rau cov zis hluav taws xob.Vim tias qhov hloov pauv tsis muaj teeb meem ntawm kev xaiv cov kev taw qhia ntawm cov dej ntws tam sim no, tsis muaj qhov sib txawv ntawm cov tswv yim thiab cov zis.Ob lub MOSFET yog qhib los yog tawm nyob rau hauv kev tswj ntawm internal inverting thiab tsis-inverting logic.Qhov kom zoo dua ntawm CMOS keyboards yog rail-rau-rail dynamic ntau yam, kev ua haujlwm bidirectional, thiab qhov kev tiv thaiv tseem tsis hloov pauv thaum lub zog hloov pauv.
