Abstract

The TGV32, a 32-channel preamplifier-multiplicity discriminator chip for the multiplicity vertex detector (MVD) at PHENIX, is a unique silicon preamplifier in that it provides both an analog output for storage in an analog memory and a weighted summed-current output for conversion to a channel multiplicity count. The architecture and test results of the chip are presented. Details about the design of the preamplifier, discriminator, and programmable digital-analog converters performance as well as the process variations are presented. The chip is fabricated in a 1.2 μm, n-well, complementary metal-oxide-semiconductor process.
