【摘要】 从斜坡补偿的基本原理出发,设计了自调节斜坡补偿电路。该电路利用Cascode电流镜将系统输出电压与输入电压差转化为电流信号,对该电流信号积分,得到可以根据系统输出电压与输入电压差自动调节斜率的电压信号并转化为自调节斜率的电流信号。该电路基于UMC0．6μm工艺设计,Spice仿真结果表明该电路输出信号线性度好。文章最后给出了仿真结果并与理论分析进行比较。更多还原

【Abstract】 On the basis of the theory of slop compensation, a self-regulation slope compensation circuit is designed. The circuit changes the difference between the input voltage and the output voltage to current signal by Cascode current mirror. Integrated the current signal, the self-regulation slope compensation voltage signal is achieved and it can be transformed to self-regulation slope compensation current signal. The circuit is designed on the basis of UMC0.6μm process. The simulation results used Spice show that the output signal has good linearity. Finally, the simulation results are provided and compared with the theory results.更多还原
