ACTIVE RECTIFIER WITH DELAY LOCKED LOOP, WIRELESS POWER RECEIVING APPARATUS INCLUDING ACTIVE RECTIFIER

摘要

PURPOSE: An active rectifier using a delay locked loop and a wireless power receiving device including the same are provided to remove a voltage drop phenomenon generated in a passive rectifier by using the active rectifier. CONSTITUTION: A first loop includes a first switch(510), a first delay switch(520), a first delay locked loop(530), and a capacitor(570). The first switch is comprised of a PMOS transistor(512). The first delay switch is conducted by a differential signal with regard to an AC signal. The capacitor generates a DC voltage corresponding to a peak amplitude of the AC signal. A second loop includes a second switch(540), a second delay switch(550), a second delay locked loop(560), and a capacitor(570).
