CURRENT THRESHOLD ELEMENT “MODULAR THREE SUBTRACTOR” Russian patent published in 2022 - IPC H03K19/21 

FIELD: radio engineering and analog microelectronics.

SUBSTANCE: invention relates to the field of radio engineering and analog microelectronics and can be used in high-speed analog and analog-to-digital interfaces for processing sensor signals. The modulo three subtractor current threshold element contains the first and second input bipolar transistors with combined bases, the first and second bias voltage sources, the third and fourth input bipolar transistors of a different type of conductivity with combined bases, the first and second current mirrors matched with the source buses power supply, reference current source, the fifth and sixth input bipolar transistors, the emitters of which are combined and connected to the power supply bus through the third reference current source, the seventh and eighth input bipolar transistors, the emitters of which are combined and connected to the input of the second current mirror, the seventh input bipolar transistor , the fourth bias voltage source, the eighth input bipolar transistor. The first and second additional input bipolar transistors are introduced into the circuit, the third, fourth, fifth, sixth, seventh and eighth additional input bipolar transistors of a different type of conductivity, the first, second, third additional current mirrors, the first, second, third and fourth additional reference current sources, first, second, third and fourth additional bias voltage sources. The circuit solution provides the conversion of input information in the current form of signals, ensuring the speed of the device.

EFFECT: increasing the speed of information conversion devices.
