中文摘要 |
MOSFET-C filter已變的越來越普遍,主要是因為電路簡單。設計者很容易利用opamps來實現,而且它的架構和主動RC濾波器很類似,這可大幅縮短設計的時間。 類比連續時間濾波器的頻率響應是由電阻、電容、電感或電導所決定,然而由於製程的變異、溫度的飄移或者元件的老化,會使得RC常數產生變化將近30%的變化。 我們提出一個應用於MOSFET-C filter的新型調整電路,在不需要外接電容的情況下,具有簡單、晶體小、低時脈參考頻率等優點。 |
Abstract |
MOSFET-C filters is popular in analog filters, the major reason is the simplicity. They are easily implemented with opamps and have similar architectures to active RC filters [1], this saves much of the design time. The frequency response of analog continuous time filters is determined by resistors, capacitors, inductors or transconductors. However, the process variation, temperature drift and aging, make the integrated RC time constants vary about 30 percent [2]~[3]. We proposed a switched-capacitor tuning circuit , which can be used in MOSFET-C Filter and the novel tuning circuit doesn’t need off chip capacitor. The novel circuit has following advantages (1). Small chip size. (2). Simplicity (3). Low reference clock frequency. |
