摘要： The present disclosure is applicable to electronic fields, and provides a voltage comparator. The voltage comparator includes a first branch, a second branch and a third branch. The first branch and the second branch both have self-biasing capabilities, and require no dedicated bias circuit. Under the same power voltage, the static power consumption of the voltage comparator is relatively low; fewer the power consuming branches exist in the circuit, and the reliability is high under low power consumption.

摘要： An adjustable current-synthesizer may generate synthesized current representative of an actual current, according to a model of a circuit that produces the actual current. The current synthesizer may under-sample a current sense signal derived from the actual current to obtain a few samples of the actual current, which are then used to adjust the synthesized current, thereby ensuring accuracy of the synthesized current. Sample values of the actual current are compared with corresponding generated values of the synthesized current to obtain offset values. In order to maintain monotonicity in the synthesizer results, the offset values are used to make adjustments to the slope of the synthesized current. The slope of the synthesized current may also be adjusted according to the slope of the actual current. Sub-Nyquist sampling of the actual current may be performed on the down-slope, with up-slope adjustments made based on the offset adjustment and down-slope adjustment.

The relay has an input contact, an output normally-open contact, and an output normally-close contact. The voltage detection module has a first voltage detection unit and a second voltage detection unit. The first voltage detection unit receives a voltage of the input contact and produces a first output voltage. The second voltage detection unit receives a voltage of the output normally-close contact and produces a second output voltage. The voltage comparison unit receives the first output voltage and the second output voltage and then compares the two voltages, thus detecting normal and/or abnormal contact statuses of the input contact, the output normally-open contact, and the output normally-close contact of the relay.

摘要： A measurement module includes a pair of input terminals, a pair of current paths connected to the pair of input terminals, and a pair of output terminals. A partition that is a non-magnetic insulating portion partitions an internal space of the measurement module into two spaces. Low-current components such as a magnetic detection element are disposed in a space different from a space in which the pair of current paths are housed. The presence of the partition allows the low-current components and the pair of current paths to be disposed close to one another, thus making it possible to reduce the size of the measurement module.
