| description | Minimum energy consumption is the primary design constraint in numerous
applications where battery or energy harvesting device is the main power source.
Subthreshold operations for such circuits have been used for low performance
requiring circuits and show significant energy savings.
In subthreshold region, the energy dissipated in the system is not a linear function of
the supply voltage, but instead the energy per operation versus the supply voltage
curve has a single minimum or optimum point of operation. The theory behind this
Minimum Energy Point occurrence as presented in literature is investigated and
described.
Further the MEP point changes with changes in load, temperature etc. To track these
changes in the MEP, tracking loop is suggested in a state of the art literature and this
loop is investigated and studied. The control circuit for such a loop is then
implemented and simulated in Cadence. Further, some improvements to this loop are
suggested and implemented in Cadence as a proof of concept. |
