ASIC latch simulation and protection system and method

Abstract

The invention relates to an ASIC latch simulation and protection system and method. The system is characterized by comprising a signal source, a voltage-charge conversion circuit, a digital voltage source, and a computer. The signal source is used for generating a voltage pulse signal and sending the voltage pulse signal to the voltage-charge conversion circuit. The voltage-charge conversion circuit is used for converting the voltage pulse signal into a charge signal and sending the charge signal to an ASIC device reading circuit, so that the ASIC device is latched or the ASIC device is inhibited from being latched. The digital voltage source is used for monitoring a power supply current value of the ASIC device reading circuit in real time and providing power for the voltage-charge conversion circuit and the ASIC device reading circuit. The computer is used for controlling the digital voltage source to be turned on or turned off according to the power supply current value monitored inreal time and a preset normal working current value. The ASIC latch simulation and protection system and method can be widely applied to the field of particle detection.
