摘要
基于PMOS衬底驱动技术设计了低压PMOS衬底驱动CMOS共源共栅电流镜电路(BDCCM),并讨论分析了其输入阻抗、输出阻抗和频率特性。BDCCM的最低输入压降要求只有0.4V,但是其输入输出线性度和频率带宽要比传统的共源共栅电流镜低,是低频低压CMOS模拟集成电路设计的新型高性能共源共栅电流镜。
Based on the PMOS bulk driven technique, a low voltage CMOS cascade current mirror （BDCCM） is presented, and then the input/output impedance and frequency characteristics are discussed. The minimal input voltage of BDCCM is about 0.4 V. Comparing BDCCM with gate driven cascade current mirror （GDCCM）, the linearity of the input/output characteristics and frequency width of BDCCM are lower. So the BDCCM is a good block for low voltage low frequency CMOS analog integrated circuits.
