Abstract

We describe the design and performance of an 8-bit Flash ADC based readout system developed for use on the cathode pads of the DELPHI High Density Projection Chamber (HPC). A dynamic range of 800:1 is obtained at input frequencies of 15 MHz using a bilinear voltage divider reference chain. Performance characteristics of the digitizing circuits for a CAMAC version of this readout system are presented. The design of a FASTBUS version is presented.
