The design of an efficient monolithic buckconverter is presented in this paper. A low swing MOSFETgate drive technique is proposed that improves the efficiencycharacteristics of a DC-DC converter. A model of the parasitic impedances of a buck converter is developed. With thismodel, a design space is described which characterizes theintegration of both active and passive devices of a buck converter onto the same die based on a 0.18 µm CMOS technology. The optimum gate voltage swing of a power MOSFETthat maximizes efficiency is shown to be lower than a standard full voltage swing. An efficiency of 88% at a switchingfrequency of 102 MHz is achieved for a voltage conversionfrom 1.8 volts to 0.9 volts with a low swing DC-DC converter. The power dissipation of a low swing DC-DC converter is reduced by 24.5%, improving the efficiency by3.9% as compared to a full swing DC-DC converter.
