Abstract
The present application discloses an amplification circuit. The amplification circuit includes an amplifier, a feedback unit, a second feedback unit, a first correlated double sampling unit, and a second correlated double sampling unit. The amplifier has a first positive input terminal, a second positive input terminal, a first negative input terminal, a second negative input terminal, a positive output terminal, and a negative output terminal. First terminals of the first feedback unit and the second feedback unit are coupled to the positive output terminal. The first correlated double sampling unit is coupled to the first negative input terminal and a second terminal of the first feedback unit, and performs a sample operation and an output operation. The second correlated double sampling unit is coupled to the second negative input terminal and a second terminal of the second feedback unit, and performs the sample operation and the output operation.
