Title: Pulse generator and its method
Inventor: EHATA HIRONARI
IPC: H03K3/78
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a pulse generator which performs phase changes with a unit that is smaller than a level change cycle of a clock of a frequency dividing object. SOLUTION: A signal SK1 is a pulse string of a cycle T that is acquired by reproducing the pulse width duty of an input clock SCK. An SK1 passes through an input CK creating circuit 6 and inputted as an SK11 to a variable delay circuit 7. The circuit 7 switches an output signal level by delaying only by a delay time td (T<td<(2/3)) at a rise of a pulse string of the SK11 and switches again the signal level after the time td at a fall of the pulse string of the SK11 after the switching of this signal level. As a result, an output DSK of the circuit 7 becomes a pulse string that has three times as a long cycle as the SK11. Also, the time td of the circuit 7 is changed within the range based on phase data by a phase controlled current source 8 and a DAC 9 and the phase of a DSK 2 is controlled.
