The interface circuit includes low noise readout circuit, Zigbee wireless transceiver, tunable RF power amplifier, and RF switch. Based on the state-of-the-art Zigbee transceiver, adding tunable RF power amplifier, and RF switching, and with appropriate algorithm, it achieves a smart energy-saving transceiver. The sensor signal and control signal are transmitted by wireless communication in lowest power consumption. The proposal executes for three years. In first year, the soft ware and hard ware of the Zigbee transceiver are accomplished to achieve the sensor and control signals transmission in wireless communication. The second year, the low noise readout circuit are designed and fabricated. The readout circuit reads sensor signal and sends the signal to the Zigbee wireless transceiver, and then transmit it to control center. The third year, the tunable RF power amplifier and RF switch are designed and fabricated, and the two circuits are integrated in a silicon chip. The Zigbee transceiver adds the chip with appropriate algorithm to achieve a smart energy-saving wireless transceiver.
