Original Abstract Submitted
a phase adjustment circuit includes a clock generation unit () which generates a sinusoidal differential clock signal; a variable amplifier () which receives a differential clock signal output from the clock generation unit () as an input, outputs an amplitude-adjusted differential clock signal, and simultaneously outputs an amplitude-adjusted in-phase signal; an adding unit () which adds an 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 () which transmits the differential signal output from the adding unit (); and a terminal circuit () which terminates the differential transmission line ().
