Clock signal supplying circuit

摘要

A clock signal generated by a clock signal generating circuit is supplied to a frequency-dividing circuit formed using a D-type flip-flop circuit, being supplied to a controlled circuit after being divided down. Furthermore, the clock signal generated by the clock signal generating circuit is supplied to the controlled circuit by way of a through circuit having signal-delay-quantity substantially equivalent to signal-delay-quantity of the frequency-dividing circuit, the through circuit being formed using the D-type flip-flop circuit in the same way as the frequency-dividing circuit.
