Two-dimensional anti-radiation low-noise current reading circuit based on trans-impedance amplifier

Abstract

The invention belongs to the technical field of integrated circuits, and particularly relates to a two-dimensional anti-radiation low-noise current reading circuit based on a trans-impedance amplifier. The invention designs a low-noise current reading circuit which takes a trans-impedance amplifier as a basic prototype and has excellent radiation resistance based on an advanced two-dimensional process. Through meticulous design, the anti-radiation low-noise readout circuit based on the trans-impedance amplifier can remarkably improve the signal-to-noise ratio of the circuit and ensure reliable capture of weak signals, and due to the excellent anti-radiation characteristic of the two-dimensional transistor, the whole circuit can still work normally in the radiation environment. The two-dimensional anti-radiation low-noise reading circuit based on the trans-impedance amplifier can be widely applied to satellite-borne electronic equipment such as a satellite communication system and a satellite sensing detection system, and a nuclear power station electronic system.
