An energy efficient level shifter is an interfacing circuit which can interface low core voltage to high input-output voltage. It address the challenges posed by simultaneous use of different supply-voltage levels on the same circuit. It allows communication between different modules without adding any extra pin. so it can easily avoid voltage mismatch problem. The main objective of the work is to minimize power dissipation in shifter, which is due to multiple supply voltages in the circuit. The model presents a new energy efficient level shifter for logic voltage shifting from subthreshold to above- threshold domain. The proposed method uses Multi-threshold Complementary metal oxide semiconductor technique, which is one of the energy efficient design technique to achieve power minimization and also to provide a wide voltage conversion. The proposed design is implemented in CADENCE Virtuoso 180-nm technology process.
