Abstract :
A high-speed range pipelined integrator and encoder ASIC for fast digitization of charge from photomultiplier tubes is under development at Fermilab. The application-specific integrated circuit (ASIC) is intended to operate in conjunction with a fast analog-digital converter (ADC) to digitize signals from a charge source over a dynamic range of 18-20 b with 8-10 b of accuracy every 16 ns. Development of the device, called QIE (charge integrator and encoder), is being carried out in an IC process with CMOS and NPN devices. Many chips have been designed and tested to prove the feasibility of the device
