High-Performance ADC Simulation at the CERN Large Hadron Collider

The ATLAS Experiment at the CERN Large Hadron Collider required the design of a custom ADC. The ADC developed for this application is a dual-channel 12-bit ADC test chip, in which each channel consists of four pipeline stages to resolve the four most significant bits, followed by an 8-bit successive-approximation-register (SAR) ADC.
