OPERATIONAL AMPLIFIER BASED BROADBAND CONVERTER FOR CONVERTING N-CURRENT INPUT SIGNALS INTO VOLTAGE Russian patent published in 2016 - IPC H03F3/45 

FIELD: radio engineering, communication.

SUBSTANCE: operational amplifier based broadband converter for converting N-current input signals into voltage comprises an input differential stage with an extended active operation range, a power source, an active load circuit and an additional stage for converting input current on a transistor on a common-base circuit with N-current inputs. The differential stage comprises a common emitter circuit, a non-inverting input, an inverting input and antiphase current outputs.

EFFECT: enabling the suppression of the inphase component of input differential current of the device.
