Zusammenfassung:	The simulation and experimental study of current-mode DC-DC boost converter is presented in this paper The DC-DC converter is designed with a standard 0.35μm BiCMOS process. The off-chip LC filter is operated with the inductance of 1mH and capacitance of 100μF. The simulation results show the high performance DC-DC boost converter. The output voltage from simulation is obtained to be 5.8V with ripple ratio of 1.5%. The result corresponds with the experimental result within 5% error. The sensing current is obtained to be within 1mA and follows to fit the order of the aspect ratio between sensing and power MOSFET.
