无锯齿频分双工和全双工收发器需要非常高的接收器线性度。自干扰消除可以放宽规范，但导致非常高的功率。我们提出了一种低功耗的直接转换单端接收机与无源SIC。一个28 nm CMOS原型实现了IB和OOB SI的有效IIP3 > 25 dBm，仅20 dB消除和25 dB隔离。功耗为25mW，有效面积为0.5mm2。
Saw-Less Frequency Division Duplexing and Full-Duplex transceivers require very high receiver linearity. Self-Interference Cancellation can relax the specification but results in very high power. We propose a low-power direct-conversion single-ended receiver with passive SIC. A 28 nm CMOS prototype achieves an effective IIP3 > 25 dBm for both IB and OOB SI with only 20 dB cancellation and 25 dB isolation. Power consumption is 25mW, active area is 0.5 mm2.
