BROADBAND VOLTAGE-TO-CURRENT CONVERTER ON FIELD-EFFECT TRANSISTORS WITH CONTROL P-N JUNCTION Russian patent published in 2020 - IPC H03F3/343 H03F3/34 H03F3/45 

FIELD: electronics; radio engineering.

SUBSTANCE: invention relates to electronics and radio engineering and can be used as converter of input voltage in proportional and antiphase output currents (VCC). Converter comprises input (1) and first (2) current output of device, matched with first (3) power supply bus, input (4) field-effect transistor, gate of which is connected to device input (1), first (5) output field-effect transistor, drain of which is matched with first (3) power supply bus, and source is connected to gate of first (5) output field-effect transistor through first (6) current-stabilizing resistor, second (7) output field-effect transistor, the drain of which is connected to first (2) current output of the device, and the gate is connected to second (8) power supply bus, the drain of input (4) field-effect transistor is connected to second (8) power supply bus, and source (5) of the first output field transistor is connected to the source of second (7) output field-effect transistor, wherein the source of input (4) field-effect transistor is connected to the gate of first (5) output field-effect transistor.

EFFECT: ensuring VCC operability at unipolar supply, as well as creation of VCC circuit with two antiphase current outputs, possibility of its application in intermediate stages of operational amplifiers.
