摘要：
A low input DC/DC converter and power manager in 0.18 μm CMOS process was presented. The proposed converter can work with the input voltage as low as 25 mV. Four logic controlled outputs provide the best voltage for various applications to accommodate low-power design requirements. Reserve energy on the storage capacitor CSTORE provides power when the input voltage source is unavailable. Simulation shows that the overall efficiency is about 64% with 300 μA load current. This work provides a complete power management solution for wireless sensing and data acquisition. © 2016, Beijing University of Posts and Telecommunications. All right reserved.
