An ABMK-1.3 analog array chip for the high-precision detection of arrival times of signals in the wide frequency range in nuclear electronics is created. The chip contains a high-speed comparator with a built-in hysteresis and low-pass filter (LPF). The propagation delay of the comparator signal does not exceed 1.25 ns, and the hysteresis of the transfer characteristic can be regulated from 40 to 200 mV. The bandwidth of the LPF is below 130 kHz. The circuit design of separate stages of the chip and experimental characteristics are given.
