DIFFERENTIATION FOR ANALOG SIGNALS PROCESSING (VERSIONS) Russian patent published in 2017 - IPC G06G7/18 

FIELD: radio engineering, communication.

SUBSTANCE: group of inventions can be used to differentiate analog signals in adaptive linear filters-compensators of high-frequency losses in high-speed data transmission lines, in measuring devices of capacitive tomography systems, neuromorphic visual sensors, in high-frequency filtering schemes, in schemes of fast calculating the predicted increment of the input signal in high-speed multibit ADC using analog prediction. In one embodiment, the device comprises a differentiating capacitor, an auxiliary amplifier having a gain of more than 1, a main signal transmission amplifier comprising a transistor connected in a common gate scheme, a current source, a load resistor.

EFFECT: increase the linearity and speed and also the accuracy of the device.
