Abstract
An amplifier includes a differential amplification block suitable for receiving and amplifying a first differential input signal and a second differential input signal; an output block suitable for determining an output signal according to a state of amplified signals outputted from the differential amplification block; and an output range restriction block suitable for controlling an output range of the output signal outputted from the output block based on a maximum clamping signal and a minimum clamping signal.
