Abstract: A reference current generator circuit suitable for low-voltage applications is provided. The generator circuit is fabricated in a chip for generating a precise reference current based on a precise reference voltage and a precise external resistor. The generator circuit provides an equivalent resistance coupled in parallel with the external resistor to provide resistance compensation and reduce the impedance of seeing into the chip from a chip pad. In addition to the resistance compensation, only moderate capacitance compensation is required to enhance the phase margin of the generator circuit, so as to achieve a stable loop. Therefore, chip area and cost can be reduced in low-voltage applications. In addition, the generator circuit reproduces the reference current generated by the external resistor by utilizing current mirrors, so as to eliminate the effect on currents caused by parallel coupling of the equivalent resistance and the external resistor.

Abstract: An event detection method is disclosed. At least one most adaptable life cycle model is generated according to at least one historical event data, at least one nutrition growing function, and at least one firing point rule. Event data is received and a strength value thereof is calculated according to a life cycle model corresponding to the event data. It is determined whether an event firing point is achieved according to the strength value variation. If the event firing point is achieved, an event corresponding to the event data is sent. The event detection method enhances the ability of event tracking and development so event firing is more accurate to fit real event occurring situations, realize event evolution, and filter false alarms.
