CMOS thiab TTL yog ob qho kev faib tawm ntawm kev sib txuas ua ke. CMOS stands rau 'Complementary MetalOxide Semiconductor', thaum TTL txhais tau tias 'Transistor-Transistor Logic '. Lub sij hawm TTL tau txais los ntawm kev siv ob BJTs (Bipolar Junction Transistors) hauv tsim txhua yam logic rooj vag.

Cov lus nug tseem yog, qhov txawv ntawm TTL thiab CMOS yog dab tsi?

Ib lub rooj vag logic hauv CMOS nti tuaj yeem muaj tsawg li ob FETs thaum lub rooj vag logic hauv TTL chip canconsist ntawm ib tug ntau yam ntawm qhov chaw raws li ntxiv Cheebtsam xws liresistors xav tau. Rau TTL , lub suab nrov yog 0.5 Vwhile rau CMOS yog 1,5v. Suab nrov tiv thaiv ntawm CMOS yog zoo heev li os TTL circuits.

Ib sab saum toj no, dab tsi yog qhov zoo ntawm kev siv CMOS logic tshaj TTL? Qhov zoo ntawm CMOS logic tsev neeg overTTL . Lub ntsiab qhov zoo ntawm CMOS logic tsev neeg yog lawv cov kev siv hluav taws xob tsawg heev. Qhov no yog vim tias tsis muaj kev coj ncaj qha los ntawm Vdd mus rau hauv av hauv ob qho tib si ntawm inputconditions.

Ntawm no, qhov twg zoo dua CMOS lossis TTL?

CMOS piv rau TTL : Txawm li cas los xij, CMOS kev siv hluav taws xob nce nrawm dua nrog lub moos nrawm dua TTL ua. Qhov qis dua tam sim no xav tau cov khoom siv hluav taws xob tsawg dua, yog li ua rau tsim kom yooj yim thiab pheej yig dua. CMOS Cheebtsam muaj ntau dua rau kev puas tsuaj los ntawm electrostatic tawm dua TTL cov khoom.

CMOS logic tsev neeg yog dab tsi?

CMOS Logic tsev neeg . CMOS (complementarymetal-oxide-semiconductor) tshuab yog siv feem ntau los tsim cov digital circuitry. Lub hauv paus tsev blocks ntawm CMOS circuits yog P-hom thiab N-hom MOSFET transistors. CMOS technology ntiav ob hom transistor: n-channel thiab p-channel.
