Patent number: 8902097Abstract: One or more techniques and/or systems described herein implement, among other things, a parabolic curve for a ramp signal in a data acquisition component, where the curve can be effectively calibrated and used to provide a settling period to mitigate noise. That is, a ramp generator can generate a ramp signal that has a parabolic voltage curve with two substantially mirroring halves. A comparator can compare a first portion of the parabolic voltage curve with a voltage signal indicative of a number of photons detected by a detection array. A second portion of the parabolic voltage curve is used as a temporal delay so that circuitry, such as the ramp generator, can settle.Type: GrantFiled: September 30, 2010Date of Patent: December 2, 2014Assignee: Analogic CorporationInventors: Matthew Bieniosek, Hans Weedon, Enrico Dolazza, Martin Choquette
