FIELD: measuring equipment.
SUBSTANCE: invention relates to the non-contact electrometer amplifiers. Non-contact electrometer amplifier has a feedback, includes an inverting integrator connected to the output of the amplifier, two series-connected p-n junctions connected by their common point to the input of the amplifier and circuit of bias of two series-connected p-n junctions in reverse direction, wherein the middle point of the bias circuit is connected to the output of the inverting integrator.
EFFECT: reduced noise level of the amplifier.
