Rashmi Sharma and Shyam Akashe
The low power and low leakage in voltage level shifter is presented in this paper. With the aim of reduce the leakage power of CMOS devices, during digital circuits construction obligatory low supply voltages and low power consumption. In the digital circuits leakage power is leading factor, which is mainly influenced to the power consumption. For low power applications, reduction in leakage power is important. High leakage currents are the major giver of total power consumption of the CMOS circuit. In advance technology, the traditional CMOS technique is compared with the self controllable switch (SVL) technique. Various leakage reduction techniques are employed for reduce leakage and power, SVL technique is one of them leakage reduction technique. In order to achieve power consumption and power dissipation, a self controllable voltage level switch is used in proposed method. Simulation is done by using cadence virtuoso environment at various supply voltage (0.3 to 1.2 V). By using this leakage optimization technique in voltage level shifter, 89% leakage power is reduced as compared to power gating technique.
