Description

A very fast low-noise low-power 64-channel front-end chip for binary readout of silicon microstrip detectors (FABRIC) has been designed and manufactured using the full-custom bipolar process SHPi by Tektronix. The circuit consists of a preamplifier, a shaper and a discriminator. A noise level of 476 e-+63 e-/pF has been obtained for the amplifier peaking time of 15 ns. The walk time of the discriminator is less than 5 ns for input signals ranging from 2 fC to 8 fC at a discriminator threshold of 1 fC. The dead time for two minimum ionizing particle signals is 40 ns. The above parameters have been obtained with a low power consumption of 1.3 mW per channel. ((orig.))
