Abstract

As there is rapid increase in daily used battery-powered electronics equipment, and as these battery-powered equipments are able to work for a limited amount of time before requiring to recharge, there is ever increasing demand for long battery life (as run time on a full charge) that can be achieved by either increasing the battery capacity or reducing power consumption by the devices. In this paper, a switch minimized parallel LFSR with clock gating technique is proposed, and further optimization of circuit is performed by reducing number of gates (transistor) used by the circuit. Dynamic power consumption is reduced by minimizing the switching activity factor of the circuit, for which we utilize clock gating technique. Proposed circuit power consumption is compared with previous LFSR. The proposed circuit is implemented and simulated in cadence at 180 nm channel length, which verifies further reduction in power as compared to previous technique.
