摘　　要：设计了一种电平移位电路,包括快速响应电路和低功耗电平维持电路,通过快速响应电路的快速响应输入的低压控制信号,产生一窄脉冲来驱动输出信号电平的建立;然后通过低功耗电平维持电路在窄脉冲结束后维持输出信号的电平.该电路适用于新一代功率器件的驱动电路,具有响应速度快和低功耗的特点,可以充分发挥新一代功率器件高工作频率和低功耗的优势.基于HHNEC 0.35μm 80VCD工艺,对提出的电平移位电路进行仿真验证,结果表明所设计的电平移位电路响应时间为2.8ns左右,功耗为21.5μA左右.A level shifter circuit,including fast response circuit and low power level sustain circuit,is proposed in this paper.A narrow pulse to drive the output signal level established is generated by quick response of the low voltage input control signal in the fast response circuit.And then the low power level sustain circuit maintains the level of the output signal after the end of a narrow pulse.The circuit is suitable for driving a new generation of power devices,with fast response and low power,can give full play to their advantages of high operating frequency and low power consumption.This circuit is based on the HHNEC 0.35μm 80 VCD process,the simulation result shows that the level shifter can response within 2.8ns and has low power consumption with 21.5μA.
