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 a first event and at a non-triggering level upon occurrence of a reference event that follows the first event. A first current circuit has a current source or a current sink. A second current circuit has a current sink or a current source. 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 and non-conducting states so that the shunt is driven to the conducting state upon receiving the trigger signal at the triggering level and is driven to the non-conducting state upon receiving the trigger signal at a non-triggering level. A current boost circuit is in communication with the capacitor.
