A fast shaping low power amplifier-comparator integrated circuit for silicon strip detectors

摘要

We have designed and tested a 64 channel amplifier-comparator integrated circuit on the Maxim SHPi bipolar process. The low power design, 840 /spl mu/W/channel, is intended for use as a frontend with high clock rate silicon strip detector systems. Peaking time at the comparator input is 20 ns, for good double pulse resolution, and noise is near optimum for the technology used. We have used the chip successfully in a proton beam test at KEK in Japan with a 40 MHz data clock.
