中文摘要：

片上集成的数字开关电源（SMPS）控制器采用数字方式的补偿器,能够实现较为复杂的控制策略以达到高性能电源管理。针对普通数字补偿器通常占用较大的片上面积问题,通过分析Boost电路模拟补偿器的数字化方法,提出了全集成的数字补偿器电路方案,并采用了非线性寻址查找存储补偿系数,实现了面积和瞬态响应优化;所提出的方案具有面积小、功耗低、结构简单、易于综合的特点。现场可编程门阵列（FPGA）验证结果表明,采用该补偿器的控制器可应用于数字电源的控制。

英文摘要：

Digital type of compenstor integrated in digital switched mode power supply（SMPS） controller can be implemented with more complicated control strategy to achieve high performance power manegement.Aiming at the large size problem of ordinary digital compensator,the digitalization of analog compensator of a Boost SMPS was analyzed.The design and optimization method of integrated digital compensator with nonlinear look up table was introduced,which was used to store the coefficient of the compensator.By the nonlinear look up table,the size was reduced and transient response was improved.The proposed architecture gains the features of small size,low power consumption,and it is easy to synthesis.The results based on field programmable gate array（FPGA） verification indicate that this compensator is suitable for digital SMPS.
