Automatic tuning system for high-frequency integrated continuous-time filters

This paper proposes an automatic tuning system for the high-frequency characteristics of integrated continuous-time filters. In the case of a filter using integrators with electrically controllable unity-gain frequencies, the frequency characteristics affected by parasitic elements can be easily compensated for without knowledge of the filter structure.
