Patent number: 7259616Abstract: The present invention provides a method for single-ended compensation of an operational amplifier, which comprises: designing an operational amplifier having a single-ended offset style, preparing a common-mode circuit, a switch circuit, a comparator, a digital circuit and a compensation circuits. When a single-ended offset voltage of the operational amplifier is converted, output of the comparator will change state and will be detected by the digital circuit, so that the digital circuit will fix a group of digital signals, and instruct the switch circuit to block an average signal of the common-mode circuit, allowing a set of double-end input signals to be inputted to the operational amplifier directly.Type: GrantFiled: May 13, 2005Date of Patent: August 21, 2007Assignee: Princeton Technology CorporationInventor: Yao Sheng Chang
