Performance Analysis of Leakage Current Reduction in Standby Mode of Zigbee SoC Using Active Mode Logic

Zigbee SoC plays an important role in transferring and receiving the data in wireless sensor networks for its data security and high speed grade. The active mode of Zigbee SoC consumes power from power supply directly and standby mode of Zigbee SoC consumes no power from the power supply unit. There may be a leakage current in standby mode of the circuit which further linearly degrades the performance of the Zigbee SoC. This paper proposes a low power and high efficient active mode logic of the power gating methodology in Zigbee SoC to reduce the leakage current. The circuit in proposed Zigbee SoC has less number of transistors than the conventional methodology and hence the proposed system has low delay as 2.29 * 10–8 ms.
