The apparatus includes an amplitude path delay obtainer configured to obtain amplitude-delay information on a delay occurring in a propagation path of an amplitude component signal, a phase path delay obtainer configured to obtain phase-delay information on a delay occurring in a propagation path of a phase component signal, a delay controller configured to calculate and output a difference between the obtained amplitude path delay and the obtained phase path delay, and a variable delayer configured to compensate for a delay by changing a delay value on the basis of the delay difference output from the delay controller. Using an asynchronous method, in which a signal obtained before and after a delay is used as the clock signal of a memory device and the clock signal of a register to find the delay, it is possible to reduce the complexity of the constitution and increase power efficiency.
