Abstract
In some embodiments, the phase adjustment circuit includes a clock generator that is configured to generate a sinusoidal clock signal, and may include a variable amplifier that is configured to receive the clock signal output from the clock generator as an input, output an amplitude-adjusted sinusoidal differential clock signal, and output an amplitude-adjusted in-phase signal. The phase adjustment circuit may include an adder that is configured to output a differential signal obtained by adding the in-phase signal to each of a positive phase side and a negative phase side of the differential clock signal output from the variable amplifier, a differential transmission line that includes two transmission lines configured to transmit the differential signal output from the adder, and a terminal circuit that is configured to terminate the differential transmission line where a signal is output from a terminal of any one of the two transmission lines.
