dc.description.abstract | 在現今的積體電路設計中,系統單晶片(SoC)是一個主流方向。鎖相迴路及相關的電路更是必須朝向SoC方面發展。隨著製程進步,電晶體的尺寸越來越小但對於被動元件的尺寸來說沒有變小。低通濾波器是鎖相迴路其中的一個區塊,是由電容以及電阻所組成。在過去的幾年中,為了降低晶片面積跟成本通常將低通濾波器設計在晶片外部。為了達到SoC的目的,希望將迴路濾波器整合進入晶片當中。然而,這些迴路濾波器在晶片當中佔了相當大的面積。由於在展頻時脈產生器中,通常會有一個較小的頻寬。所以在較小的頻寬下會造成較大的低通濾波器。如果我們欲降低此迴路濾波器的面積,可以利用一個除二電路來達到此目的。 | zh_TW |
dc.description.abstract | Today System-on-Chip (SoC) is a mainstream for integrated-circuit design. PLLs are essential for SoC. The transistor size becomes much smaller when the CMOS process is improved, but not for on-chip passive components. A low-pass filter which is composed of capacitors and resistors is one of the building blocks in PLL. In the past years, a low-pass filter is always designed off-chip to reduce the chip size and production cost. Nowadays, a low-pass filter integrated into a chip is preferred for SoC. However, these passive components will occupy large area in a chip. We usually use a smaller bandwidth in a spread spectrum clock generator (SSCG), thus it will lead to a larger low-pass filter in the SSCG system. Since we want to reduce these passive components, a novel divided-by-two circuit is proposed and used in the PLL. | en |
