Abstract
An embodiment is a phase adjustment circuit includes a sine wave output circuit, a first multiplier, a second multiplier, and an adder. The sine wave output circuit is configured to output two sine wave signals of a fixed phase difference. The first multiplier is configured to multiply an amplitude of a first sine wave signal output from the sine wave output circuit by a first variable to generate a first output signal. The second multiplier is configured to multiply an amplitude of a second sine wave signal output from the sine wave output circuit by a second variable to generate a second output signal. The adder is configured to add the first output signal from the first multiplier and the second output signal from the second multiplier.
