Abstract
A phase compensation circuit includes: a first circuit that increases phase characteristic of a specific frequency of an electrical signal; a second circuit that decreases the phase characteristic of the specific frequency of the electrical signal; and a limiting amplifier that amplifies an electrical signal that is processed by at least one of the first circuit and the second circuit.
