The noise fluctuation amounts AVSX and Δ in the two output signals % and Vy are offset from the power supply fluctuation amount. Thus, when the level determination is performed, the noise fluctuation amounts Δ~, Δ can be obtained. The ideal sensed signal w, in turn, achieves a high-precision measurement capability for level determination. It is worth mentioning that although the bran is cautious &,, 〇..., the above example uses the two-dimensional way of the first and second output signals W, vy to measure the level, but for the actual need only The device for measuring the dimensional level (the first output signal Vx) is also the same.
