DELAY CONTROL DEVICE
First Claim
1. A delay control device that receiving inputs of a first input pulse signal and a second input pulse signal and outputting a first output pulse signal and a second output pulse signal having a relative delay time near a predetermined target value, the device comprising:
- a first input end receiving the input of the first input pulse signal;
a second input end receiving the input of the second input pulse signal;
a first output end outputting the first output pulse signal;
a second output end outputting the second output pulse signal;
a first signal route part having two or more signal routes with different delay times;
a second signal route part having two or more signal routes with different delay times;
a first switch having one connection end formed of two or more terminals connecting one end of each of two or more signal routes of the first signal route part and another connection end formed of one terminal;
a second switch having one connection end formed of two or more terminals connecting one end of each of two or more signal routes of the second signal route part and another connection end formed of one terminal; and
a control part outputting a control signal to the first switch and the second switch so that a relative delay time between the first output pulse signal and the second output pulse signal is near the target value, the control signal for selecting any one of the terminals of the one connection end of the first switch and connecting the selected terminal to the terminal of the other connection end of the first switch and for selecting any one of the terminals of the one connection end of the second switch and connecting the selected terminal to the terminal of the other connection end of the second switch, whereinthe first signal route part and the first switch are connected between the first input end and the first output end, andthe second signal route part and the second switch are connected between the second input end and the second output end.

Abstract
A delay control device that controls a relative delay time between two signals and is easy to be miniaturized is provided. Signal routes 111 to 114 and signal routes 121 to 124 in a first signal route part 110 and a second signal route part 120 have different delay times. By selecting any one of the four signal routes 111 to 114 in the first signal route part 110 and any one of the four signal routes 121 to 124 in the second signal route part 120, it is possible to finely change a relative delay time between two input pulse signals.
