ABSTRACT:
A time interval analyzer for measuring time intervals between events in an input signal includes a trigger circuit that receives an input signal and that outputs a trigger signal at a triggering level upon occurrence of the event. A first current circuit has a constant current source or a constant current sink. A second current circuit has (1) a current sink where the first current circuit has a constant current source or (2) a current source where the first current circuit has a constant current sink. A capacitor and a shunt are operatively disposed in parallel with respect to the first current circuit. The shunt is disposed between the first current circuit and the second current circuit. The shunt receives the trigger signal and is selectable between conducting an non-conducting states between the first current circuit and the second current circuit, depending upon the trigger signal, so that the shunt is driven to the conducting state from the non-conducting state upon receiving the trigger signal at the triggering level.
