Abstract :
Minimizing power consumption in multi-processor systems requires the use of multiple supplies with a wide range of regulated voltages and currents. Since one inductor per DC-DC converter is expensive, there is an increasing interest in single-inductor-multiple-output (SIMO) DC-DC converters. Recent research results report a SIMO boost converter and various boost or buck converters with two outputs. This 0.5mum CMOS system is a four- output, single-inductor buck converter with independent regulation of each output.
