Abstract:
A circuit to generate a servo burst signal, including a circuit to generate a first differential signal and a second differential signal, a first half wave rectifier to rectify the first differential signal and to generate a first rectified signal, a second half wave rectifier to rectify the second differential signal and to generate a second rectified signal, a first peak detector to detect a first peak of the first rectified signal, a second peak detector to detect a second peak of the second rectified signal, and a circuit to generate the servo burst signal based on the first peak signal and the second peak signal.
