Abstract:
A method for calibrating a bandwidth of a phase-locked loop begins with detecting an error signal generated by the phase-locked loop in response to a stimulus signal. The difference between the integral of the error signal and a nominal value thereof is computed, and the bandwidth of the phase-locked loop is adjusted based on the computed difference.
