ANALOGUE-TO-DIGITAL CONVERTER Russian patent published in 2021 - IPC H03M1/50 

FIELD: measuring equipment.

SUBSTANCE: invention relates to analogue-to-digital measuring electronics, in particular, to analogue-to-digital converters with intermediate voltage conversion in pulse duration. The analogue-to-digital converter comprises a digital synchronous counter 1, a digital parallel register 2, a frequency-phase detector 3, a low-pass filter 4, a voltage-controlled generator 5, a digital frequency divider 6. The output of the digital parallel register 2 is made in the form of an output bus and constitutes the output of the apparatus. The low-pass filter 4 is based on an active integrating link with two resistive blocks.

EFFECT: increase in the accuracy of converting an analogue signal.
