Abstract: Disclosed is an amplifier including a first transistor and a second transistor to which differential input signals are applied to gate terminals thereof, respectively, a second transistor having a first end connected to the first transistor, a gate terminal receiving a first bias signal, and a second end outputting a first differential output signal of a differential output signal pair, a fourth transistor having a first end connected to the second transistor, a gate terminal receiving a second bias signal, and having a second end outputting the a second differential output signal, and a pair of capacitors coupled to the second transistor and the fourth transistor, and having a cross-coupled structure with respect to each other.
