Abstract :
A new technique for tuning high-Q continuous-time filters is presented. This technique is a modified version of an adaptive tuning method where the tuning signals are sinusoids generated by digital bandpass delta sigma oscillators. As will be shown, the required building blocks for the tuning system are simple. Simulation results are presented to show the feasibility of the proposed approach
