Ultra-Low Power m-Sequence Code Generator using New XOR Gate for Body Sensor Node Applications

Body Sensor Nodes (BSNs) are devices which are used to improve and monitor human health by means of transmitting and receiving the data through transceivers wirelessly and are nowadays being used extensively in medical fields. The m-Sequence code generator is used in the transceiver in order to achieve spread spectrum transmission technique. In this paper an ultra-low power m-Sequence code generator is proposed in order to achieve low power consumption. The proposed m-Sequence code generator is designed using D-Flip-Flop based Linear Feedback Shift Register (LFSR) and new XOR gate. The proposed new XOR gate has low power dissipation, better PDP and high driving capability. The proposed designs are simulated using Cadence Virtuoso 90nm CMOS technology.
