Amplification circuit with split-length compensation scheme
An amplification circuit includes: a current source; a first input transistor pair suitable for receiving a positive input voltage and having a split-length gate structure; a second input transistor pair suitable for receiving a negative input voltage and having a split-length gate structure; an enable unit suitable for supplying a current from the current source to each of the first input transistor pair and the second input transistor pair in response to an enable signal; a switching unit suitable for coupling a second split gate node between the second input transistor pair to a compensation capacitor node during an activation section of the enable signal; and a compensation driving unit suitable for compensating and driving a first split gate node between the first input transistor pair at an initial stage of the activation section of the enable signal.
