IPC: H03K5/04
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To control a clock duty to a fixed value, without requiring an external circuit. SOLUTION: A D flip-flop circuit 110 generates a pulse CKH of a cycle 2T. A count circuit 120 counts a reference delay step number DREF, corresponding to one cycle of CK and outputs it to a duty control circuit 130. The duty control circuit 130 calculates a delay setting step number value DREFH corresponding to the delay time. When the duty ratio is 50%, the value of DREFH becomes 1/2 that of DREF. A delay line 140 outputs the pulse CKH after delaying it for time corresponding to the delay setting step number value DREFH. In this case, a delay signal DCKH delayed for T/2 is generated and outputted to a clock generating circuit 150 as shown in the figure. In the clock generating circuit 150, a clock CK1 is outputted by exclusive ORing the pulse CKH of the cycle 2T and the delay signal DCKH delayed for T/2. As a result. the clock CK1 of 50% duty can be provided.
