摘要翻译：
在此之前，我们提出了一种用于全双工(FD)无线的非磁、非互易N路滤波器的环行器-接收机（CIRC.-RX）结构，它将基于换相的线性周期时变(LPTV)非磁环行器与下变频混频器合并，在其输出端直接提供基带(BB)接收机信号，同时抑制了一组换向开关的噪声贡献。该架构还结合了一个片上平衡网络，以增强发射机(TX)-接收机(RX)隔离。在本文中，我们给出了详细的结构分析，包括噪声分析和平衡网络的影响分析。通过对65 nm CMOS 750 MHz环行器-接收机样机的仿真和测试，验证了分析的正确性。环行器-接收机可处理高达+8 dBm的TX功率，在20 MHz RF带宽(BW)下具有8 dB噪声系数(NF)和40 dB平均隔离度。结合数字自干扰(SI)及其三阶互调(IM3)消除，FD Circ.-Rx在高达+8 dBm TX平均输出功率下表现出80 dB的整体SI抑制。还通过FD演示验证了所述权利要求，其中在发送0dBm平均功率类ofdm TX信号的同时恢复了-50dBm微弱的期望接收信号。

英文摘要：
  Previously, we presented a non-magnetic, nonreciprocal N-path-filter-based circulator-receiver (circ.-RX) architecture for full-duplex (FD) wireless which merges a commutation-based linear periodically-time-varying (LPTV) non-magnetic circulator with a down-converting mixer and directly provides the baseband (BB) receiver signals at its output, while suppressing the noise contribution of one set of the commutating switches. The architecture also incorporates an on-chip balance network to enhance the transmitter (TX)-receiver (RX) isolation. In this paper, we present a detailed analysis of the architecture, including a noise analysis and an analysis of the effect of the balance network. The analyses are verified by simulation and measurement results of a 65 nm CMOS 750 MHz circulator-receiver prototype. The circulator-receiver can handle up to +8 dBm of TX power, with 8 dB noise figure (NF) and 40 dB average isolation over 20 MHz RF bandwidth (BW). In conjunction with digital self-interference (SI) and its third-order intermodulation (IM3) cancellation, the FD circ.-RX demonstrates 80 dB overall SI suppression for up to +8 dBm TX average output power. The claims are also verified through an FD demonstration where a -50 dBm weak desired received signal is recovered while transmitting a 0 dBm average-power OFDM-like TX signal.
