Design and Analysis of Priority Encoder with Low Power MTCMOS Technique

In recent trends power optimization is becoming one of the most important factor in integrated circuits today. Low power MTCMOS technique has appeared as an encouraging technique to decrease power dissipation, leakage currents and leakage power. High performance priority encoder was designed using MTCMOS technique and compared with conventional CMOS technique. Comparative analysis showed that how these techniques were used to optimize the average power and shows significant improvement in terms of speed. After the comparative analysis, it has been concluded that as compared to the conventional design, MTCMOS technique reduced power by 37% at 90nm and 21% at 45nm. Leakage current is reduced to 54% at 90nm and 96% at 45nm. Moreover, energy consumption was also reduced to 32% at 90nm and 20% at 45nm. This paper addresses remarkable uses of low power techniques in high speed digital circuits, mobile phones and high operating frequencies.
