Apr 1, 2023· Power management in electronic systems is primarily targeted toward two purposes. First is to minimize heat dissipation in order to improve the system''s usability (for handheld devices and wearables), reliability (for safety- and mission-critical systems), etc. Secondly, the power management methods may target the minimization of the system''s energy consumption.
previous efforts at power reduction have focused on dynamic power sources because static power due to leakage current has been a small fraction of the total power dissipated by a chip. However, as transistor threshold voltages are reduced, subthreshold leakage current increases dramatically. Fig. 1 shows estimated static power consumption due
One of these is the issue of power dissipation. Indeed, power delivery and dissipa-tion are becoming primary limiters of performance and integration for microprocessors.
