Mobile equipment such as organic-EL display, digital still camera and so on re-quire both positive and negative power supply voltage to obtain high quality. Single InductorMultiple-Output (SIMO) DC-DC converter can provide a pair of positive and negative outputvoltages with only one external inductor. This paper describes SIMO DC-DC Converter usingproposed current-mode control (CMC) circuit. The proposed CMC circuit realizes high responsespeed for the change of load current. Spectre simulations with 0.18[removed info]m CMOS process parameterare performed to verify the validity of the proposed converter. The simulation results indicatethat the proposed converter has higher response time compared with conventional converter.
