Investigation Of Various Shaping Methods For The Development Of A Fully-Monolithic Cmos Constant-Fraction Discriminator, Robert Gentry Jackson
Investigation Of Various Shaping Methods For The Development Of A Fully-Monolithic Cmos Constant-Fraction Discriminator, Robert Gentry Jackson
Masters Theses
In this work the design of a constant-fraction discriminator (CFD) fabricated in the Orbit Semiconductor l.2-Jl n-well CMOS process is presented. This timing pick-off circuit is designed for use in the readout electronics of the Lead-Scintillator subsystem of the Pioneering High Eenergy Nuclear Ion eXperiment (PHENIX) Electromagnetic Calorimeter at the Relativistic Heavy Ion Collider (RHIC). The design was driven by stringent requirements including low power consumption, small area, arrayable, low cost and a fully integratable shaping network. Various integratable CFD shaping methods are investigated, and the candidate methods chosen for fabrication were the distributed R-C delay-line shaping, lumped-element R-C shaping …
