This article presents a novel wide operational range reconfigurable regulating rectifier for wireless power transfer. The proposed 1X/2X/3X rectifier achieves wide range voltage regulation without global loop control to minimize the area occupation. Compared with previous work, more working modes and greater magnification allow the proposed rectifier to regulate smaller signal, which extends voltage regulation range. A novel local loop control system is proposed for voltage rectification with three modes. The local loop adaptively senses the duty cycle of mode signal to determine which two working modes the rectifier should work with and configure the rectifier in these two modes. Then the rectifier are switching between two working modes according to the comparison result with reference voltage. Also, the change of which two working modes are also triggered by a window comparator to make sure the change happens when the output voltage is far away from reference voltage. The system is designed and simulated in a 0.18um BCD technology. The measurement results show that the proposed system can rectify wide-range input AC power to a regulated output. The achieved voltage conversion ratio (VCR) is 0.95-2.68 with a peak power conversion efficiency (PCE) of 87.4%.
