The APV25 is the readout chip for silicon microstrips in the CMS tracker. It is the first major chip for a high energy physics experiment to exploit a modern commercial 0.25μm CMOS technology. Experimental characterisation of the circuit shows full functionality and excellent performance before and after irradiation. Automated probe testing of many chips has demonstrated a very high yield. A summary of the design, detailed results from measurements, and probe testing results are presented.

Abstract
The APV25 is the readout chip for silicon microstrips in the CMS tracker. It is the first major chip for a high energy physics experiment to exploit a modern commercial 0.25μm CMOS technology. Experimental characterisation of the circuit shows full functionality and excellent performance before and after irradiation. Automated probe testing of many chips has demonstrated a very high yield. A summary of the design, detailed results from measurements, and probe testing results are presented.
