发明名称 Replica DLL for phase resetting
摘要 A method, algorithm, architecture, circuits, and/or systems for using a delay-locked loop (DLL) for phase adjustment in a direct conversion radio receiver are disclosed. The DLL is configured to avoid a perceived phase shift when the control voltage to a delay line is reset upon reaching a predetermined amount. Embodiments disclosed include a DLL, a radio receiver using the DLL, a circuit for resetting the DLL, a method for recovering a modulated radio signal, and a method of synchronizing a reference clock to a radio signal. The approach can allow for improved synchronization of the reference clock to a received radio signal during baseband frequency recovery.
