Embodiment Construction
[0038] The present invention will be further described below in conjunction with accompanying drawing.
[0039] figure 1 It is embodiment 1 of a multi-interval voltage comparator, and the output multi-interval voltage comparison value is composed of 7-bit binary numbers, and each bit corresponds to one of the seven voltage intervals 1-7 of the input voltage U1. figure 1 Among them, the voltage dividing resistors RF1-RF7 form a voltage dividing circuit. After dividing the voltage of the power supply +VCC1, the obtained 6 threshold voltages UF1-UF6 are 6 intermediate separation voltage values that divide the input voltage U1 into 7 intervals. The six comparators FA1-FA6 realize the comparison between the input voltage U1 and the six threshold voltages UF1-UF6, and the output multi-interval voltage comparison value is composed of the output Y11-Y16 of the six comparators FA1-FA6 and the highest interval judgment value Y17. The input voltage U1 is sent to the inverting input te...
