Low power discriminator for ATLAS pixel chip
[article]
2009
Preserved Fulltext
The design of the front-end (FE) pixel electronics requires low power, low noise and low threshold dispersion. In this work, we propose a new architecture for the discriminator circuit. It is based on the principle of dynamic biasing and developed for the FE chip of the ATLAS pixel upgrade. This paper presents two discriminator structures where the bias current depends on the presence of a signal at the input of the discriminator. Since the activity in the FE chip is very low, the power
