摘　　要：基于Dickson电荷泵结构,提出了一种适用于反熔丝现场可编程门阵列(FPGA)的新型高效电荷泵电路,实现了电荷泵的快速启动。通过采用时钟信号升压电路,减少了电荷泵级数,并减小了电路总体面积和功耗。仿真结果显示,在2.5 V的工作电压和整体电路全负载的条件下,整体电路的启动时间约为20μs,可稳定输出电压5.46 V,工作电流约为618μA。采用0.18μm CMOS工艺流片并对其进行编程和测试,结果显示FPGA电路编程成功,功能正确,与仿真结果一致,表明了此电荷泵结构的可行性和实用性。Based on the Dickson charge pump structure,a novel high efficient charge pump circuit suitable for anti-fuse field programmable gate array(FPGA)was proposed,which realized the quick start of the charge pump.By using the clock signal boost circuit,the number of charge pump stages was reduced,and the overall area and power consumption of the circuit were also reduced.Simulation results show that under the working voltage of 2.5 V and full load of the whole circuit,the start-up time is about 20μs,the stable output voltage is 5.46 V and the working current is about 618μA.The circuit was fabricated with 0.18μm CMOS process and was programmed and tested.The results show that the FPGA circuit is programmed successfully and the function is correct,which is consistent with the simulation results,indicating the feasibility and practicality of this charge pump structure.
