Power Management and Sleep Modes - ppt download
{"Image DocumentName": "Power Management and Sleep Modes", "Image ImageDescription": "A key feature of many microcontrollers is low power consumption. The principle way to reduce power consumption is to stop the clock. Quiescent CMOS consumes essentially no power at feature sizes > .35u. CMOS power dissipation is mostly due to dynamic power dissipation, i.e., power dissipation caused by signals transitioning. For example, in the DEC Alpha microprocessor (~1995) approximately. 50% of the 30W dissipated was spent in simply driving the clock tree. Rough figure for power dissipation in CMOS: (neglicting leakage) Pd = CV2f. where C = capacitance, V = voltage, f = frequency of operation.", "Image XResolution": "300", "Image YResolution": "300", "Image ResolutionUnit": "Pixels/Inch", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
