| Popis: | Wireless sensor networks for monitoring and sensing applications have grown steadily in recent years. These applications are composed of swarm of sensor nodes within close proximity. Typical nodes have a limited power supply and the communications block usually has the largest percentage in the total power consumption. Current trends are geared towards low power design and to address this, three gain settings on the main data receiver’s intermediate frequency stage was incorporated to the system based on the transmitter and receiver distance range of 1 m to 10 m. A wake-up receiver was also integrated with the main data receiver, taking the role of idle listening as the main receiver is in sleep mode. The main receiver has a sensitivity of -50 dBm to -70 dBm and consumes 4.14 mW of power, while the wake-up receiver has a sensitivity of -50 dBm and consumes 13.73 µW of power. An energy efficiency of 4.1 nJ/bit and 138 pJ/bit are achieved by the main and wake-up receivers, respectively. Up to 90% of power savings can be achieved as long as the main receiver duty cycle does not go beyond 96%. The estimated area of the integrated receiver chip layout is 1.634 sq. mm. |
