“…To quantify the key system parameters of each block, the typical values of the parameters are summarized in Table 1. The proposed system is designed to operate with a channel bandwidth (B) of 5 GHz, 16-QAM modulated signal (SNR 𝑈 =SNR 𝐶𝑈 of > 18 dB) and 40m-link range to a user equipment receiver with 𝑁 𝐹 𝑟𝑢 =𝑁 𝐹 𝑈𝐿 of 8 dB [15], which yields a path loss 𝐿 𝑃𝑎𝑡 ℎ = 94.0𝑑𝐵 at 30 GHz.

This article presents a novel chip-scale 25-45-GHz re-configurable mm-wave remote antenna unit (RAU) for radio over fiber (RoF) distributed antenna systems. The proposed RAU architecture optimizes energy efficiency by operating directly at mm-wave frequencies, and spectral efficiency by selecting re-configurable RF photonic filters topology. Additionally, it achieves frequency agility by rejecting interferes and a small form factor by utilizing SOI photonics process. Two photonic integrated circuits (PICs) that act as downlink and uplink units are presented while occupying a total area of 12.33 mm$^2$. The downlink selects a single channel within the desired frequency range, while the uplink rejects up to four interferes. The building blocks of the proposed architecture are discussed and their design consideration and parameters are shown. Then, a comprehensive system analysis of the proposed RAU architecture including key performance indicators is presented. A scalable 5-channel system is demonstrated each with a 3-dB Bandwidth of 5-GHz. Moreover, this architecture can be continuously tuned and re-configured within a wide frequency range to cover all 5-channels. To the best of the authors’ knowledge, this is the first wideband modular and re-configurable mm-wave RAU that covers the entire mm-wave sub-45-GHz band implemented in silicon photonics.

“…Generating NOP for beyond 10 GHz operation would require frequency dividers operating >20 GHz, leading to increased power for LO generation. Technology scaling to 45 nm RFSOI, series inductor to resonate input capacitance, use of small mixer switch sizes, and a LO scheme relying on passive quadrature generation followed by transmission gates to generate ∼25 % duty-cycle waveforms are used in [61] to demonstrate a 4-phase mixer-first RX operating from 20 GHz to 30 GHz with 8 dB NF and 41 mW power consumption(Fig. 19).…”

Fragmented spectrum allocations at RF and mm-Wave, increased use of carrier aggregation/MIMO and dense spectrum-reuse in wireless links has led to interest in the design of integrated wideband, high-linearity MIMO RX that provide low noise, blocker tolerance and reconfigurability across signal domains. In this paper, receive architectures for wide operating range and blocker tolerance are presented with a focus on recent developments in reconfigurable N-path receivers. Generalized sequence-mixing architectures that support reconfigurable frequency/spatial/code-domain rejection and filtering are described along with directions of research extending operation to wider bandwidths and higher frequencies.INDEX TERMS N-path filters, reconfigurable receivers, current-mode, passive mixers, sequence mixers, spatio spectral filtering, walsh function sequence based notch filters, blocker tolerant receivers, blocker tolerant MIMO, interference tolerant receivers.This article has been accepted for inclusion in a future issue of this journal. Content is final as presented, with the exception of pagination.

“…The dynamic power consumption is due to the clock buffers driving the mixer switches, while the static power consumption is due to the radio frequency (RF) low noise amplifier (LNA) [8]- [11] and the baseband (BB) trans-impedance amplifier (TIA). In recent years, [12]- [39] have employed a passive mixer as the first block of the receiver instead of an LNA. Mixer-first receivers [12]- [39] offer many advantages over traditional LNA-first receiver architectures [1]- [3], [5], [6], making them suitable for nextgeneration software-defined radios (SDRs).…”

This paper presents a four-phase passive mixer-first receiver using a common-gate (CG) trans-impedance amplifier (TIA), instead of a conventional shunt-feedback amplifier. The four-transistor TIA used in this work combines current-reuse with cross-coupled g m-boosting to achieve a reduced noise figure (NF) at low power levels. Moreover, complementary derivative-superposition (CDS) linearization within the TIA helps to improve the linearity with no additional power overhead. A prototype receiver is implemented in a 180 nm CMOS technology. The receiver operates from 0.3 to 1.3 GHz with a conversion gain of 21.9 dB. In measurements, the receiver achieved a noise figure of 5.8 dB and an in-band (IB) IIP3 of +7.2 dBm while consuming 0.34 mW power per TIA at 1 GHz. The measured spurious-free dynamic range (SFDR) at 1 GHz is 76.9 dB. INDEX TERMS Common-gate trans-impedance amplifier (TIA), current-reuse, g m-boosting, low-power, mixer-first, N-path filter, passive mixer, tunable, wideband.
