2results about How to "Avoid serious deviation" patented technology

The application relates to the technical field of integrated circuits, and discloses a digital auxiliary adaptive zero-crossing detection circuit. The circuit comprises a digital auxiliary comparator module, a digital logic module, a detection discrimination module and a counter module. The digital auxiliary comparator module compares a switch node voltage signal with a power ground signal to generate a first output signal; the digital logic module processes the first output signal to generate a zero-crossing detection signal and control the turn-off of a power tube; the detection discrimination module receives a second output signal of the digital logic module and the zero-crossing detection signal to generate a digital tuning signal; and the counter module receives the digital tuning signal to generate a six-digit digital signal, dynamically adjusts a resistance array in the digital auxiliary comparator module, adaptively adjusts the flip offset of the comparator by changing the resistance value of the resistance array, and thus changes the turn-off timing of the power tube. The application can accurately control the turn-off timing of a synchronous rectification power tube, reduce the reverse current and reduce the dynamic power consumption.

This invention relates to the field of quantitative trading technology and provides a method and system for intelligent risk management in quantitative trading. The invention involves monitoring the trading environment in conjunction with other systems, acquiring manually input reference trading data when there are no risks, acquiring historical trading data and automatically generated quantitative trading data, performing profit and risk analysis, calculating the trading overlap rate when expected conditions are met, and determining whether the overlap conditions are satisfied. If the overlap conditions are satisfied, quantitative trading is executed. This system can acquire historical trading data, manually input reference trading data, and automatically generated quantitative trading data, perform profit and risk analysis, calculate the trading overlap rate when expected conditions are met, and then execute quantitative trading when the overlap conditions are satisfied. This ensures the security, compliance, and efficiency of quantitative trading while preventing the results from deviating significantly from the user's expectations, thus ensuring the stability of quantitative trading.
