JOINT-INTEGRATION ANALOG-TO-DIGITAL CONVERTER Russian patent published in 1995 - IPC

FIELD: pulse technique. SUBSTANCE: analog-to-digital converter has integrator, three switches, comparator, threshold element, voltage divider, current source, two integrating elements, current-limiting resistor, two selector switches, counter, flip-flop, AND and OR gates, reference voltage integrating time shaping unit, and control unit. Novelty is introduction of voltage-controlled current source and second current-limiting resistor, and also new interconnections among other components which provide for elimination of complementary conversion errors thereby improving accuracy of analog-to-digital converter. EFFECT: improved accuracy of converter due to elimination of errors. 5 dwg
