摘要

PROBLEM TO BE SOLVED: To provide a signal generation device in which a clock signal different in an "H" period and an "L" period can be generated by a simple structure.;SOLUTION: A counter 107 counts a clock CLK. When a count value is matched with a setting value of a resistor 102, a comparison circuit 108 sets an output OVF to be "H", and a signal generation part 10 formed of an EXOR circuit 105 and a flip flop 106 changes a logical value of an output clock CLKOUT. A selector 109 selects and outputs either of two inputs SLI1 and SLI2 in accordance with the logical value of the output clock CLKOUT. The counter 107 receives an output SLO of the selector 109 as a count enable signal.;COPYRIGHT: (C)2005,JPO&NCIPI
