Patent number: 11374581Abstract: A technology related to an electronic circuit, specifically, a phase locked loop or a frequency synthesizing apparatus, is disclosed. The frequency synthesizing apparatus includes an injection locked frequency divider and a replica frequency divider having the same circuit configuration as the injection locked frequency divider. A control value required for self-oscillating at a target frequency using the replica frequency divider is determined. When the injection locked frequency divider fails injection locking on a first attempt, the injection locking may be attempted using the determined control value. On the first attempt, the control value of the injection locked frequency divider may be determined and stored in advance according to a temperature and a supply voltage.Type: GrantFiled: July 26, 2021Date of Patent: June 28, 2022Assignees: SKAIChips Co., Ltd., Research & Business Foundation SUNGKYUNKWAN UNIVERSITYInventors: Kang Yoon Lee, Jong Wan Jo, Young Gun Pu, Byeong Gi Jang, Joon Hong Park, Dong Soo Park, Jae Bin Kim, Yun Gwan Kim

Patent number: 9876440Abstract: Disclosed herein is an active rectifier. The rectifier includes a rectifier unit, a driver unit, and a switching device control circuit unit. The rectifier unit includes first and fourth transistors configured to become conductive when the voltage of an alternating current (AC) input is negative and apply the current of the AC input to a rectifier capacitor, and second and third transistors configured to become conductive when the voltage of the AC input is positive and apply the current of the AC input to the rectifier capacitor. The driver unit outputs first to fourth drive control signals, and drives the first to fourth transistors. The switching device control circuit unit compares the first drive control signal and the second drive control signal with the AC input, and outputs switching device control signals to delay the first to fourth drive control signals based on the extents to delay.Type: GrantFiled: December 29, 2016Date of Patent: January 23, 2018Assignee: Research & Business Foundation Sungkyunkwan UniversityInventors: Kang Yoon Lee, Seong Jin Oh, Youngoo Yang, Keum Cheol Hwang, Young Jun Park, Sang Yun Kim, Byeong Gi Jang, Jung Yeon Kim
