High impedance input for connecting voltage source to voltage-processing circuit, e.g. for electrochemical sensor

摘要

The input connects a voltage source to a circuit having an input impedance of at least 10<11> OMICRON and arranged on a circuit board. The sections (10) of the circuit board (4) for the input are isolated from the remaining sections by a separating gap (8). A connection is provided to the processing circuit. The gap may be 0.1-2 mm wide. Also claimed is a measurement processing device, a circuit board, and a method of manufacturing a high-impedance input.
