Abstract
Analog sum-and-buffer amplifiers have been developed to provide a fast trigger signal from the lead-glass electromagnetic calorimeter in the TOPAZ detector for TRISTAN e/sup +/e/sup -/ collider experiments. The total kick-back noise from the 4300-channel gate signals of the LeCroy FASTBUS ADC 1885N has been suppressed to less than 40 mV (equivalent to a 0.4-GeV electron signal). The performance of the amplifiers is described.<>
