Study on anomalies of integrated operational amplifier induced by proton deep charge-discharge effects

With the gradual development of the aerospace industry towards deep space exploration, the frequency of space activities in harsh space environments such as the Van Allen Belt, the surface of Mars, or other planets in the solar system is gradually increasing The radiation environment encountered by spacecraft in interplanetary deep space orbits is mainly composed of solar protons and galactic cosmic rays. When a large number of high-energy protons gather in the spacecraft's dielectric materials, it will induce charging and discharging effects, thereby affecting electronic devices This article takes the LM124 operational amplifier circuit as a research example, and uses a medium to high energy proton accelerator to study the characteristic laws of anomalies induced by deep space proton induced deep charge discharge effects in the circuit.

At the same time, combined with HSPICE simulation methods, the sensitive areas and mechanisms of the discharge pulse action operational amplifier circuit are studied
