All digital energy sensing for minimum energy tracking
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2014•ieeexplore.ieee.org
Minimizing energy consumption is of utmost importance in an energy starved system with
relaxed performance requirements. This brief presents a digital energy sensing method that
requires neither a constant voltage reference nor a time reference. An energy minimizing
loop uses this to find the minimum energy point and sets the supply voltage between 0.2 and
0.5 V. Energy savings up to 1275% over existing minimum energy tracking techniques in the
literature is achieved.
