  • Self-feedback type low-noise charge sensitive amplifier
    Patent number: 4053847
    Abstract: A so-called charge sensitive amplifier is used as a pre-amplifier for a semiconductor detector. A field-effect transistor (FET) is used as the input stage of the amplifier, wherein the gate terminal of the FET is fed back from the output of the amplifier and the drain terminal of the FET is grounded through a capacitor and connected to a constant current source to make the drain voltage change correspond to the gate potential. The gate potential is self-stabilized.
