【Abstract】 In this paper a new high-speed analog summing circuit will be introduced in brief. It can receive multi-channel analog signals and processes them to sum. It will output a signal of 50mV for each channel when it is trigged by low amplitude signals (≥20mV). The impedance of analog summing circuit is 50Ω. The summing circuit delay 19ns. The output signal of circuit can be used on the system of datum acquisition to MUDAL to generate trigger signal. It also can be used to discriminate multi-coincidence events.更多还原
