Power supply solution for DDR bus termination
By Robert Kollman, Senior Applications Manager, Power Management John Betten, Applications Engineer, Power Management and Bang S. Lee, Application Specialist, Power Management Introduction
Power dissipation in CMOS logic systems is related to the clock frequency, the input capacitance of the various gates within the system, and the supply voltage. As device feature sizes, and hence supply voltages, have been reduced, significant gains have been made in lowering system power dissipation. Reduced dissipation and higher operating speeds of these lower-voltage devices have allowed system clock frequencies to be pushed into the hundreds of megahertz. At these very high clock frequencies, clock distri……
