Preserved Fulltext
A digital scheme for automatic tuning of continuous-time high-filters is proposed. The tuning scheme uses the phase information for both frequency and -factor tuning, therefore, the relationship between the filter's passband magnitude and is immaterial. Due to the digital control of the tuning loops, only one loop is active at a given time interval, which eliminates the need for a slow tuning loop, improves stability and reduces tuning time. Experimental breadboard tests verify the operation
