Publication number: 20080180138Abstract: The invention relates to method of determining a fractional division ratio using a sigma-delta modulator. In this method, the fractional division ratio of the sigma-delta modulator is set as k/q, where k is an integer input value of the sigma-delta modulator, and q is a value preset to determine a predetermined frequency resolution. A spur generated from the voltage controller oscillator according to the variation of k is measured while the value k is varied. When the spur takes place at a certain value of k where a frequency is lower than a predetermined reference frequency, the fractional division ratio is reset as k/(q+1) or k/(q?1) for the certain value of k. The reset fractional division ratio is provided to the divider.Type: ApplicationFiled: September 19, 2006Publication date: July 31, 2008Applicant: SAMSUNG ELECTRO-MECHANICS CO., LTD.Inventors: Sung Cheol SHIN, Yoo Hwan KIM, Ki Sung KWON, Yo Sub MOON

Patent number: 7282969Abstract: The invention provides a low divide ratio programmable frequency divider of a fractional-N type applied to a digital MOPLL tuner and a method thereof. In the invention, a divide ratio assigner assigns divide data as a main divide ratio and a pulse swallow value according to a first or a second dividing operation mode in response to a mode selection signal. A prescaler operates on the first or second divide operation mode in response to the mode selection signal. Also, a main counter divides a frequency from the prescaler by the main divide ratio. Further, a pulse swallow counter counts a clock of the main counter while outputting a pulse swallow signal to the prescaler. The pulse swallow signal has a swallow level if a counting value corresponds to the pulse swallow value, and a non-swallow level if the counting value does not correspond to the pulse swallow value.Type: GrantFiled: April 28, 2006Date of Patent: October 16, 2007Assignee: Samsung Electro-Mechanics Co., Ltd.Inventors: Sung Cheol Shin, Yoo Hwan Kim, Ki Sung Kwon, Soo Woong Lee, Jin Taek Lee, Yo Sub Moon
