Digital tuning of high-order high-Q continuous-time filters Academic Article uri icon


  • A digital tuning scheme for automatic tuning of high-order high-Q continuous-time filters is proposed. The scheme uses phase information for both centre frequency and Q tuning, and does not rely on the relation between the passband gain and Q factor. Digital control of frequency and Q tuning loops improves the stability by enabling only one loop at a given tuning cycle. High-order filter tuning is performed without separating individual sections, eliminating switches and their parasitics.
