Abstract
Current-sensing circuit is one of the important analog units in a current-control-mode DC-DC converter. This paper analyzes the advantages and disadvantages of commonly current-sensing circuit. And then a high performance high-precision current-sensing circuit without additional power consumption is designed. This circuit is simulated with Spectre simulator which is based on HHNEC BCD 0.35μm process model. The results show that the advantages of this circuit is simple and easily realized. This circuit has been integrated successfully into some Boost DC-DC convertor chips.关键词
