Abstract
The Letter proposes the tuning of monolithic continuous-time filters employing a successive approximation algorithm to control the automatic adjustment of a two-integrator loop to its nominal resonant frequency depending on an error signal provided by a digital phase discriminator. This achieves high-precision tunability which does not depend on tight circuit matching.Keywords
