Abstract :
This paper presents a low-voltage integrated current-mode boost converter designed with a standard TSMC 3.3/5 V 0.35-mum CMOS technology. The proposed circuit could be operated for nickel metal hydride, fuel cell and alkaline battery-powered applications. The low-voltage and high-efficiency boost converter can successfully boost IV supply to 3.3 V due to four proposed circuit structures, including PMOS power-switch integration, zero-current detector, ring oscillator and driving buffer. The simulation results show that the power efficiency is higher than 90% for 110 mA load current at 1.5 V supply.
