“…The best integrated canceller implementations, in terms of antenna interface efficiency shown in Table 3, include [53] (in 45 nm CMOS), [60] (in 28 nm CMOS), and [62] (in 40 nm CMOS), all of which are amplitude and phase-based cancellers and have a canceller efficiency of >70%. Such a high efficiency is attributed to their low power consumption where [53] and [60] use completely passive implementations, while the canceller reported in [62] has a DC power consumption of only 0.25 mW. In addition, the NF degradation introduced by these implementations is very low.…”

Full-duplex (FD) wireless -simultaneous transmission and reception on the same frequency -is a promising technique that can significantly improve spectrum efficiency and reduce communication latency in future wireless networks. To enable FD operation, the powerful self-interference (SI) signal leaking from the transmitter (TX) into the receiver (RX) needs to be suppressed and canceled to an extreme degree at the antenna interface as well as in the RF/analog and digital domains. Various approaches to achieve TX-RX isolation at the antenna interface and SI cancellation (SIC) in the RF/analog and digital domains have been demonstrated, with a focus on using bench-top off-the-shelf components. Recent advances in integrated circuit (IC) implementations of various types of shared antenna interfaces and cancellers in the RF and/or analog baseband (BB) domains have further pushed the frontier of realizing FD wireless in small-form-factor/hand-held devices. Moreover, it is still important to fundamentally study the SIC performance that can be achieved by different types of cancellers. In this paper, we present a first-of-its-kind comprehensive overview on the implementation and comparison of various state-of-theart integrated shared antenna interfaces and SI cancellers in both the RF and analog BB domains. We define two figures of merit (FOM) for the IC-based shared antenna interfaces and SI cancellers, which capture various design considerations and performance tradeoffs including the achievable isolation/SIC, bandwidth, noise figure degradation, TX/SI power handling, and power consumption. In particular, we focus on two types of integrated shared antenna interfaces including electrical-balance duplexers and circulators. We also discuss two types of SI cancellers based on the time-domain and frequency-domain approaches, which respectively employ parallel delay lines and bandpass filters to emulate the SI channel. Based on realistic measurements, we perform extensive numerical evaluations to illustrate and compare the achievable RF SIC performance in different scenarios, as well as discuss various design tradeoffs. Finally, we provide an overview of the IC-based implementations and performance evaluations of both types of cancellers based on our recent work.

“…In addition, the nonlinear behavior of the power amplifier (PA) and the TX LO harmonics generate unwanted harmonic content of the TX (Type D). These harmonics may degrade the performance of the RX when they fall in-band and on top of the desired RX signal [30]. For a transceiver operating in an interband CA scenario, the condition to have large voltage swings, requiring only weak coupling paths for unwanted LO crosstalk.…”

This article presents a comprehensive survey of the literature on self-interference (SI) in long-term evolution advanced (LTE-A) and fifth-generation (5G) new radio transceivers and should serve the reader as a guide and starting point for further work on SI management. Current trends in cellular transceiver designs are discussed, and reasons why new technologies, such as carrier aggregation, cause potential sensitivity degradation due to self-interfering signals are highlighted. The survey provides an overview of the most common interference mechanisms and continues with a taxonomy on SI mitigation architectures by comparing the strengths and weaknesses of various techniques.

“…Furthermore [17] has much higher power dissipation and higher NF. In [12] power dissipation is very low but the maximum SI is only −20 dBm. However, to be fair, it must be noticed that all of the other works reported in the table report measured results, while in this work we are presenting only simulation results.…”

“…When the canceler is turned on, the P 1dB is pushed to 5 dBm, as plotted in Figure 18b. This work is benchmarked against prior works focussing on SI cancellation for FDD and fullduplex systems [12,17,19,20] as shown in Table 1. The system achieves low noise figure and high effective IIP3 thanks to the improvement of the canceler cross-modulation distortion, while dissipating low power.…”

An active self-interference (SI) cancellation technique for SAW-less receiver linearity improvement is proposed. The active canceler combines programmable gain and phase in a single stage and is co-designed with a highly-linear LNA, achieving low noise and low power. A cross-modulation mechanism of the SI canceler is identified and strongly suppressed thanks to the introduction of an internal resistive feedback, enabling high effective receiver IIP3. TX leakage of up to −4 dBm of power is suppressed by over 30 dB at the input of the LNA, with benefits for the entire receiver in terms of IIP3, IIP2, and reciprocal mixing. The design was done in a 40 nm CMOS technology. The system, including receiver and active SI canceler, consumes less than 25 mW of power. When the canceler is enabled, it has an NF of 3.9-4.6 dB between 1.7 and 2.4 GHz and an effective IIP3 greater than 35 dBm.
