LOGIC PROCESS-BASED LEVEL CONVERSION CIRCUIT OF FLASH FIELD PROGRAMMABLE GATE ARRAY (FPGA)

A logic process-based level conversion circuit of a flash flash field programmable gate array (FPGA) performs three-stage level conversion by using three conversion modules. A first-stage conversion module is configured to convert an input first signal of a VDD-GND voltage domain into a second signal of a VP1-GND voltage domain, an intermediate-stage conversion module is configured to convert the input second signal of the VP1-GND voltage domain into a third signal of a VP1-VN voltage domain, and a drive-stage conversion module is configured to convert the input third signal of the VP1-VN voltage domain into a drive signal of a VP2-VN voltage domain and output a drive word line. The logic process-based level conversion circuit reduces the pressure of conversion at each stage, ensures a capability of driving the next stage, increases the conversion speed, and provides a large driving capability at the last stage.
