A monolithic charge-sensitive preamplifier based on N-channel junction field-effect transistors (NJFETs) and P-channel MOS (PMOS) has been realized for applications with multielectrode detectors in elementary particle physics. Radiation resistance tests carried out with the preamplifier exposes to gamma-rays by a 60Co source have shown no degradation in equivalent noise charge up to 150 krad absorbed dose.
