Time-tag impulses & zero-crossing


Posted on Mar 19, 2013

Figure 1 shows the typical output from a spectroscopic amplifier, where the presence of a large amount of detector noise with Gaussian distribution is a limiting factor for system performance in amplitude and timing resolution. The time-tagging of such pulses is subject to two well-known types of errors: the jitter related to the noise and the `walking time` arising from the amplitude variation of the signals.



In Figure 2, an arming discriminator with a fixed threshold of 100 mV (5½§VRMS(NOISE)) enables the IC1, a MAX941 zero-crossing discriminator, via the first half of IC2, an HC4538 resettable monostable multivibrator. The propagation delay in these ICs al
