Patent number: 9048820Abstract: A high-speed fully differential clock duty cycle calibration circuit applied to calibrating the clock duty cycle in a high-speed system. The circuit detects the duty cycle with a continuous time integrator, and directly adjusts the duty cycle on a clock transmission link so as to increase the working speed. Being of a fully differential circuit structure, the circuit can calibrate the duty cycle under a designated process within a higher and wider frequency range, and has relatively good constraining force for process mismatch and common mode noise. The circuit comprises adjustment level ADJ1 and ADJ2, a first buffer level BUF1, a second buffer level BUF2 and a duty cycle detection level DCD.Type: GrantFiled: August 18, 2011Date of Patent: June 2, 2015Assignee: SOUTHEAST UNIVERSITYInventors: Longxing Shi, Danhong Gu, Junhui Gu, Jianhui Wu, Wei Zhao, Zhiyi Ye, Dahai Hu, Meng Zhang, Hong Li
