(簡述關於此技術之習知技術及其缺點) 與之前變壓器回授電路相比,所提出的電感的架構有下列四個好處: 1. 所提出的抽頭式電感由一個電感器所組成,而變壓器則是由二個電感器所組成,因此所提出的晶片電路面積幾乎是變壓器回授電路的一半。 2.從DC至自振頻率前,所提出之電路,皆是呈電感性,因此適合做低頻電路的應用。而變壓器回授電路,則是在DC-低頻附近是先呈電容性,之後才在自振頻率前,才是呈電感性。 3.所提出之電路,其抽頭式電感之電感值幾乎都全貢獻到等效電路的電感值,呈現高感值的電路; 相反地,變壓器回授電路,只有Primary電感,才對等效電路的電感值有貢獻,而secondary電感,對等效電感值,則完全無作用。 4.所提出之電路,其產生之負電阻,會比變壓器回授電路來的大,代表著所需要的功率消耗,會來得比傳統電路小。 Compared with conventional transformer-feedback architecture, the proposed circuit features the following good points. 1. The proposed tapped-inductor consists of one inductor, and the transformer consists of two inductors. Therefore, the chip area of the proposed method is smaller than that of the transformer. 2. The proposed circuit is inductive from DC to self-resonant frequency, thus is suiltable for low-frequency applications. However, the transformer-feedback architecture is capacitive from DC to low frequencies. 3. The equivalent inductance of Q-enhanced inductor is contributed by the proposed tapped inductor. However, the equivalent inductance of Q-enhanced inductor is merely contributed by the primary inductor of the transformer. 4. Compared with other Q-enhanced works, the proposed inductor not only compensates resistive losses with low-power consumption but also provides a high-inductance inductor which facilitates its potential use in RF filters.
