Abstract
The TGV32, a 32-channel preamplifier-multiplicity discriminator chip for th e multiplicity vertex detector (MVD) at PHENIX, is a unique silicon preampl ifier in that it provides both an analog output for storage in an analog me mory and a weighted summed-current output for conversion to a channel multi plicity count. The architecture and test results of the chip are presented. Details about the design of the preamplifier, discriminator, and programma ble digital-analog converters performance as well as the process variations are presented. The chip is fabricated in a 1.2 mu m, n-well, complementary metal-oxide-semiconductor process. (C) 1999 American Institute of Physics. [S0034-6748(99)04403-2].
