A novel on-chip current-sensing technique, which is suitable for a current-mode control CMOS DC-DC buck converter, is presented in this paper. The proposed current sensing circuit doesn't need an op amp as a voltage mirror, and thus fewer transistors are need and lower power consumption is achieved. We use the TSMC 0.35/spl mu/m 2P4M CMOS process to design and simulate the converter circuits. Simulation results show that accuracy of current-sensing for the proposed circuit is 98.2% and the core… CONTINUE READING
