Abstract

一种调压电路，包括：第一开关单元(1)、第二开关单元(2)、第三开关单元(3)、第一比较控制单元(4)、第二比较控制单元(5)和负载(6)。第一开关单元和第二开关单元均接收来自电源(VDD)的电压输入，用于将第一输出电压(VVDD)提供给负载；第一比较控制单元与第一开关单元连接，用于基于第一输出电压、第一参考电压(Vref1)和第二参考电压(Vref2)，确定第一偏置电压，以利用第一偏置电压通过数字控制方式控制第一开关单元的等效电阻的大小；第二比较控制单元分别与第三开关单元和第二开关单元连接，用于基于第一输出电压、第二输出电压(VDR)和第三参考电压(Vref3)确定第二偏置电压，并利用第二偏置电压通过模拟控制方式控制第三开关单元和第二开关单元的等效电阻的大小。该调压电路能够保证在宽泛输出电流范围内实现较高的电源抑制比。
