Title:
TRIGGER CIRCUIT AND TRIGGER SIGNAL GENERATING METHOD
Document Type and Number:
Japanese Patent JP2010166560
Kind Code:
A
Abstract:
To generate a trigger signal from a differential signal at high bandwidth and with low jitter.
The differential signal from a differential signal source 201 is applied to a non-inverted input terminal and an inverted input terminal of a comparator 211 via resistance attenuators 219 and 220. Differential threshold voltage levels from voltage sources 203 and 204 are applied to the non-inverted input terminal and the inverted input terminal of the comparator 211 via termination resistors 207 and 208. When voltages at the non-inverted input terminal and the inverted input terminal cross each other, the comparator 211 generates a trigger signal form a trigger output terminal 214.
