Wireless networks of sensor nodes are envisioned to be deployed in the physical environment to monitor a wide variety of real-world phenomena. Wireless Sensor Networks (WSNs) are becoming popular in military and civilian applications such as surveillance, monitoring, disaster recovery, home automation and many others. WSN demand low power and low cost transceiver design. The power consumed by node transceiver electronics is non-negligible and has a major impact on battery life. This paper is to design a low power transceiver for indoor application.
