SPECTROMETER BASE LINE STABILIZER Russian patent published in 1997 - IPC

FIELD: nuclear electronics. SUBSTANCE: device has amplifying section with pulsed negative feedback applied through null-comparator with gating paraphrase outputs and through ideal differential integrator; series-connected between information input and gating input of null-comparator are twin comparator with thresholds installed symmetrically relative to zero and isolating CR circuit with shortened recovery time upon gating pulse passage. Device operates efficiently within amplitude range of 200:1 at fill factor of d = n_in•T_W ≥ 200%, where n_in is intensity of spectrometric pulses; T_W is their base length. EFFECT: improved reliability of device operation. 5 dwg
