High insulation low pass filters (LPFs) are often useful to improve the step stability of the Josephson array. However ordinarily available capacitors of high insulation at DC usually show a large transient leakage effect when the polarity of input voltage is reversed. A low leakage LPF with polarity reverse switch was made to reduce the transient leakage effect. The characteristics and its effect...Show More
