摘要：
A complete 1.9GHz receiver, with BAW resonator-referenced input matching network is designed as a wakeup receiver for wireless sensor networks. The 90mn CMOS chip includes RF amplifier, PGA, ADC, and reference generation, while consuming 65 mu W from a single 0.5V supply. The input RF bandwidth of the receiver is 7MHz, while the maximum data rate is 100khps. When detecting a 31-bit sequence, the receiver exhibits -56dBm sensitivity for 90% probability of detection.
