DIFFERENTIAL VOLTAGE-CURRENT CONVERTER WITH WIDE RANGE OF LINEAR OPERATION Russian patent published in 2018 - IPC H03F3/45 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electronics and radio engineering and can be used as a wide-range device for converting the input differential voltage into a proportional output current. Result is achieved through the organization of an additional high-speed channel for the transmission of input signals. Consequence of the proposed circuit solution is the reduction of conversion errors, as well as an increase in the loop gain factor for the voltage of devices based on a differential converter, for example, operational amplifiers, voltage regulators, and so on.

EFFECT: reduced error in converting the differential converter input voltage (DCIV) into its output current, including in the high-frequency range, an increase in the upper cut-off frequency (f_u) DCIV, as well as an increase in the output resistance (r_out) DCIV.
