Kuv tsim cov rooj vag transistor sib txawv me ntsis ntau dua li lwm cov kws siv hluav taws xob. Cov neeg feem coob thaum lawv tsim rooj vag transistor; tsim lawv nrog tsuas yog cov laj thawj zoo hauv siab, txawm li cas los xij rooj vag hauv ICs muaj ob lub logic, cov laj thawj zoo thiab cov laj thawj tsis zoo. Thiab kuv tsim kuv lub rooj vag transistor nrog cov laj thawj zoo thiab tsis zoo.

Txawm hais tias muaj yim lub rooj vag; Tsis, Inverter lossis Tsis, Thiab, Nand, lossis, Tsis yog, Xor, thiab Xnor, lawv tau tsim los ntawm peb lub rooj sib tham. Thiab thaum koj tab tom tsim lub rooj logic ob lub logic, peb lub voj voos siv los tsim lub rooj vag yog Inverter lossis Tsis, Nand, thiab Tsis yog, lub qhov rooj tas yog ua los ntawm ob lossis ntau dua ntawm peb lub rooj vag no.

Vim li cas tsim rooj vag transistor? Zoo ntawm no yog tsib yam laj thawj los tsim koj tus kheej lub rooj vag.

1. Koj tsis muaj lub qhov rooj koj xav tau.

2. Koj xav tau lub rooj vag uas nqa lub zog ntau dua li lub rooj vag txheem IC.

3. Koj tsuas xav tau ib lub rooj vag thiab koj ntxub nkim qhov rooj ntawm IC.

4. Tus nqi, ib lub transistor Inverter tsawg dua $ 0.25 thiab hex Inverter IC yog $ 1.00 thiab nce.

5. Koj xav nkag siab cov rooj vag zoo dua.
