Abstract :
Based on the bulk driven PMOS transistor, a low voltage CMOS cascade current mirror (BDCCM) is presented, then the input/output impedance and frequency characteristics are discussed. Based on the simulation and test results of the TSMC 0.25 ¿m 2P4M CMOS process, the minimal input voltage of BDCCM is about 0.3 V. Comparing BDCCM with gate driven cascade current mirror (GDCCM), the input/output linear characteristics and frequency width of BDCCM is lower. So the BDCCM is a good block for low voltage low frequency CMOS analog integrated circuits.
