但實際情況卻相差很遠(yuǎn),并不是電容越大對高速電路越有利,反而小電容才能被應(yīng)用于高頻。濾波電容用在電源整流電路中,用來濾除交流成分,使輸出的直流更平滑。去耦電容用在放大電路中不需要交流的地方,用來消除自激,使放大器穩(wěn)定工作。旁路電容用在有電阻連接時,接在電阻兩端使交流信號順利通過。關(guān)于去耦電容蓄能作用的理解去耦電容主要是去除高頻如RF信號的干擾,干擾的進(jìn)入方式是通過電磁輻射。而實際上,芯片附近的電容還有蓄能的作用,這是第二位的。

光通信是一門古老的技術(shù)。通常,手是光調(diào)制器,眼睛是光探測器,光在空氣中傳播。顯然,這樣的光通信有許多缺點,它不能適應(yīng)現(xiàn)代電子學(xué)發(fā)展的要求。1966年Kao和Hockham提出用低損耗光纖導(dǎo)光,從而解決了光在大氣中傳播的不穩(wěn)定因素,使遠(yuǎn)距離導(dǎo)光成為可能。利用光纖研制光纖傳感器始于1977年,該技術(shù)一問世即引起人們的極大興趣,目前光纖傳感器已經(jīng)得到異常迅猛的發(fā)展。光纖傳感器發(fā)展十分迅速的主要原因,是它具有其他傳感器不可媲許多優(yōu)點。

兩點之前近刻度的舍入誤差就是量化噪聲的物理表現(xiàn)形式。所有ADC都會對連接至其輸入端的電壓執(zhí)行這種操作。它們會進(jìn)行信號檢測并將實際電壓近似為有限數(shù)量的步長。ADC中所用到的步長數(shù)量決定分辨率的大小。高精度Δ-ΣADC的噪聲成形特性通常會限度地降低熱噪聲和閃爍噪聲。對于16位或16位以下的器件而言,熱噪聲遠(yuǎn)遠(yuǎn)小于因信號近似而產(chǎn)生的誤差。在此類ADC中,大家會發(fā)現(xiàn)在低數(shù)據(jù)速率下數(shù)字代碼幾乎沒有發(fā)生變化。
