Abstract
An amplifier includes a first input circuit, a second input circuit, a first compensation circuit, a second compensation circuit. The first input circuit changes a voltage level of the negative output node based on a first input signal. The second input circuit changes a voltage level of the positive output node based on a second input signal. The first compensation circuit changes the voltage level of the positive output node based on the first input signal. The second compensation circuit changes the voltage level of the negative output node based on the second output signal.
