Two VLSI CMOS ICs for digital X-ray 2-D imaging system: low noise front-end amplifier and 80 MHz digital encoder interface

Abstract

We describe a VLSI-based data acquisition to perform X-Y coincidences with a two side microstrip digital detector, optimized for applications in digital mammography. A two components chip set is described in detail: a low noise Front-End analog amplifier and an 80 MHz synchronous digital encoder. These two components can be used to solve the problems arising with the use of a large number of channels and low signal amplitude as in our application.
