Patent number: 9281836Abstract: Provided is an integrating analog-digital converter. According to the present examples, the resistance against external noise is improved by incorporating a differential amplifier into an integrating analog-digital converter. Some examples also include a section where an input voltage and a reference voltage are simultaneously blocked such that switching noise may be minimized and a reference voltage may also be stably supplied. Further, examples are designed to manage a residue, which may be generated when an integral operation to an analog input value is finished, to be processed not in an additional converter but in control logic itself, thereby reducing a size of a circuit device.Type: GrantFiled: November 10, 2014Date of Patent: March 8, 2016Assignee: Magnachip Semiconductor, Ltd.Inventors: Dae Ho Lim, Yong Sup Lee
