PURPOSE:To change a delay time and a signal width without changing the circuit by using a delay circuit possible for programming the delay time and the signal width. CONSTITUTION:A unit signal generating circuit 5 receiving an output of a program command circuit 4 generated to program optionally the delay time and the output signal width generates a unit signal US. After the unit signal US is corrected by a correction circuit 6, the result is inputted to a relative value generating circuit 8. The circuit 8 receives an output of the circuit 4 to set the outputted delay time and signal width according to the relative value with a basic clock CKS. Then delay output signal generating circuits 101-104 to which the output of the circuits 4, 8 is applied generates a delay signal. Thus, the delay time and signal width are changed without changing the circuit. |
