Abstract
The article discusses the design and circuitry features of the signal reading device of the time-projection chamber of the multi-purpose detector for the nuclotron based ion collider facility. Electrical schematic diagrams, circuit simulation results, and a simplified layout for the MH2XA031 master slice array are presented. The developed signal readout device allows for a wide range of key parameter variations. For example, varying the value of one external capacitor from 5 to 100 pF provides a corresponding change in the output pulse width at half maximum from 150 to 370 ns and an equivalent noise charge from 2130 to 1570 electrons.
