Abstract

Considering the stray-capacity interference in small capacitance detection in ECT system,the stray capacitance in FPGA-based ECT system was analyzed,including that in sensors,parasitic capacitance in high-speed PCB and the crosstalk between integrated circuit chip pin and electrode lead.The corresponding measures against stray capacitance were proposed to ensure a signal accuracy and completeness in data acquisition and transmission.
