Patent number: 7834794Abstract: The conventional A/D converter has a drawback that the conversion precision is degraded when the operation periods of the constituents of the A/D converter are shortened due to the duty ratio of an external input clock because the operation periods of the constituents of the A/D converter depend on the pulse width of the external input clock. However, a highly-precise A/D conversion operation independent of the duty ratio of the external input clock can be realized by providing a circuit for detecting the operation periods of the constituents of the A/D converter, and adjusting the duty ratio of the operation clock according to the detected operation periods of the constituents of the A/D converter.Type: GrantFiled: August 10, 2007Date of Patent: November 16, 2010Assignee: Panasonic CorporationInventors: Masakazu Shigemori, Koji Sushihara, Kenji Murata
