Power reduction is one of the biggest challenges in CMOS integrated circuit design. Optimization of power is inevitable in order to reduce package cost and extended battery life. As a switch tri-modal Multi-Threshold CMOS (MTCMOS) switch can be considered as a low power solution for data retentive power gating applications. In MTCMOS, transistors with multiple threshold voltages are used in order to optimize power. The tri-modal switch provides three different power modes: active, drowsy and sleep.
