A Low power-Linear Feedback Shift register (LP-LFSR) with encoding technique is proposed. The LP-LFSR is a low power pseudo random sequence generator, designed using the True Single Phase Clock (TSPC) and gray encoding technique. It offers very high speed even while working with low power, less area and reduced clock-skew problems. Validation of the proposed design is made through comparison with a True Single Phase Clock (TSPC) based LFSR. The deployment of the LP-LFSR for testing application generates the random pattern with a single bit variation, thus leading to reduction in switching power. © Springer India 2016.
