TWO-CHANNEL ANALOGUE-TO-DIGITAL CONVERTER Russian patent published in 2018 - IPC H03M1/36 

FIELD: measuring equipment.

SUBSTANCE: proposed two-channel analogue-to-digital converter contains a key, a single-channel analogue-to-digital converter, a multiplexer with two registers on its outputs, and a shaper of the switching pulses whose output is connected to the control input of the key and multiplexer. The inputs of this two-channel analogue-to-digital converter are the inputs of the key channels, its outputs are the outputs of the registers, the output of the single-channel analogue-to-digital converter is connected to the input of the multiplexer. A short pulse shaper and an additional key, switched between the output of the first key and the input of a single-channel analogue-to-digital converter, are inputted to said converter. The second input of additional key is shorted and control input of this additional key is connected to the output of switching short pulse shaper, the input of which is connected to the output of the switching pulse shaper.

EFFECT: invention solves the problem of reducing the error.
