TTL電路是晶體管-晶體管邏輯電路的英文縮寫(Transister-Transister-Logic ),是數字集成電路的一大門類.它采用雙極型工藝制造,具有高速度低功耗和品種多等特點. CMOS是:金屬-氧化物-半導體(Metal-Oxide-Semiconductor)結構的晶體管簡稱MOS晶體管,有P型MOS管和N型MOS管 之分.由 MOS管構成的集成電路稱為MOS集成電路,而由PMOS管和NMOS管共同構成的互補型MOS集成電路即為 CMOS-IC( Complementary MOS…

1.Noise Margin 不管是TTL还是CMOS Logic Level,都会有门限.如,5V CMOS的VoutH > 4.4V, VoutL <0.33V;而它对应的输入电平VinH >3.5 , VinL <1.5V.所以,这里5V COMS的noise margin为VnH=4.4-3.5=0.9V. 为什么要有Noise Margin?因为信号在传输的时候会有噪音引入,同时,肯能会因为线路阻抗的不匹配而有发射信号在传输线上回荡.原本4.4V的高电平,加些乱七八糟的信…
