Inverter, method of operating the same and logic circuit comprising inverter

摘要

Provided are an inverter, a method of operating the inverter, and a logic circuit including the inverter. The inverter may include a load transistor (T1) and a driving transistor (T2), and at least one of the load transistor and the driving transistor may have a double gate structure. A threshold voltage of the load transistor or the driving transistor may be adjusted by the double gate structure, and accordingly, the inverter may be an enhancement/depletion (E/D) mode inverter.
