PROBLEM TO BE SOLVED: To provide a circuit for supplying a clock signal to a load having a clock input section which suppresses power consumption.SOLUTION: A clock generation section 11 generates a clock signal 13 having an amplitude corresponding to an absolute value of a potential difference between a lower limit value of a high level input voltage Vand an upper limit value of a low level input voltage Vfor a load 20 having a clock input section 21. A level shift section 12 causes a potential shift while maintaining the amplitude of the clock signal 13 such that a high level potential of the clock signal 13 is not less than the lower limit value of the high level input voltage Vand that a low level potential of the clock signal 13 is not more than the upper limit value of the low level input voltage V. A clock signal 14 with the potentials thus shifted by the level shift section 12 is supplied to the clock input section 21. |
