High frequency sampler trigger circuits including signal feedback to regulate switching times of trigger circuits

Claim 1

A SAMPLING CIRCUIT COMPRISING: A PAIR OF REGENERATIVE TRIGGER MEANS, EACH OPERATIVE ONLY IN EITHER ONE OF TWO OPERATING STATES IN RESPONSE TO A SIGNAL APPLIED THERETO ATTAINING A SELECTED THRESHOLD VALUE TO PRODUCE AN OUTPUT SIGNAL INDICATIVE OF THE OPERATIVE STATE OF THE TRIGGER MEANS; A GENERATOR FOR PRODUCING A PAIR OF SAMPLING COMMAND PULSES, EACH HAVING A TIME-VARYING AMPLITUDE BETWEEN THE LEADING AND TRAILING EDGES THEREOF; MEANS CONNECTED TO SAID TRIGGER MEANS FOR APPLYING THERTO THE COMBINATION OF A SIGNAL TO BE SAMPLED AND SAID SAMPLING COMMAND PULSES FROM SAID GENERATOR FOR ADVANCING THE TIME AT WHICH ONE OF SAID TRIGGER MEANS CHANGES OPERATING STATES IN RESPONSE TO SAID COMBINATION OF SIGNALS ATTAINING SID THRESHOLD VALUE AND FOR DELAYING THE TIME AT WHICH THE OTHER TRIGGER MEANS CHANGES OPERATING STATES IN RESPONSE TO SAID COMBINATION OF SIGNALS ATTAINING SAID THRESHOLD VALUE;
