In this paper, integrated BiCMOS amplifier and current-sensing circuits are introduced for high-performance DC–DC boost converter. By exploiting the advantage of BiCMOS technology, the high gain amplifier and accurately sensed inductor current are obtained in the feedback control circuit. The proposed current-sensing circuit adopts a current-mirror instead of op-amplifier as a voltage follower so...
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...
