摘　　要：针对反熔丝FPGA编程模式和用户模式不同的控制要求,基于Dickson电荷泵结构提出了一种新型的片上闭环电荷泵结构。新增加零伏电路实现了高电压与低电压之间有效隔离。电荷泵闭环控制机制有效地解决了启动慢的问题,保证了电路正确工作时序。仿真结果显示:在电源电压3.3 V、整体电路全负载的条件下,启动时间为6.23μs。采用0.18μm 1P3M 3.3 V/5 V CMOS工艺流片,电路编程成功并且功能正确。According to the different control requirements of anti-fuse FPGA programming mode and user mode,a new on-chip closed-loop charge pump structure was proposed based on Dickson charge pump structure.The purpose of effective isolation between high voltage and low voltage was achieved by adding a new zero-voltage circuit.The charge pump closed-loop control mechanism effectively solves the problems of slow start-up,and ensures the correct operation sequence of the circuit.The simulation results show that the starting time is 6.23μs under the condition of power supply voltage of 3.3 V and full load of the whole circuit.Taping-out with 0.18μm 1P3M 3.3 V/5 V CMOS process,the circuit is programmed successfully,the function is correct.
