“…With a 3.5 dB lower LO power, the proposed technique enables the mixer to get a similar conversion gain as that without the LO shaping, which is desirable in mmW applications. Table I summarize the circuit performance and make comparisons with the state-of-art 60 GHz mixers [9]- [14]. From the table, we can see the proposed mixer presents better IP1 dB than active mixers with similar LO power.…”

A mmWave (mmW) passive mixer topology based on a novel LO waveform-shaping technique using non-linear transmission line (NLTL) is proposed. The NLTL is constructed using series inductors and shunt varactors. It boosts the LO signal swing and reshapes the LO waveform to have higher amplitude and narrower pulses, resulting in higher gain, better linearity, and lower Noise Figure (NF) of the mixer. Mixers operating at 60 GHz are designed and implemented using 65 nm CMOS process. Simulation results show the mixer with the proposed technique obtains an NF of 5.5 dB, an input-referred P 1 dB (IP 1 dB ) of 0 dBm, and a voltage conversion gain of 1.2 dB with 0 dBm LO signal and zero dc power consumption. Silicon measurement results show that the proposed LO shaping technique improves the conversion gain by 2.5 dB and the IP 1 dB by 3 dB. Index Terms-Millimeter wave (mmWave/mmW), mixer, nonlinear transmission line.

“…For example, to support the 9 GHz range from 57 to 66 GHz, the synthetizer, working at halved frequency should generate signals from 28. [36] for the RX stages following the LNA. Therefore, with an LNA gain of 15 dB, the noise figure F RX of the whole receiver chain is de facto determined by the LNA noise figure.…”

“…The peak gain at 60 GHz is above 20 dB. The circuit topology is similar to that proposed in [36], although in this work the LNA input stage is sized to match the 50 Ω impedance of the off-chip antenna. The transistor widths in the 2 stages have been sized considering a current density of 0.15 mA/µm to optimize the noise figure.…”

This work explores the potentiality of millimeter waves (mmW) as physical layer in industrial wireless networks. Innovative models and a link design method are proposed to achieve reliable communication, at a distance of tens of meters for a single hop, even in harsh environments. By exploiting the worldwide-free band of several GHz, available around 60 GHz, mmW links allow to achieve a performance boosting of up to two orders of magnitude, w.r.t. conventional sub-6 GHz wireless links, in indoor industrial environments. Time slotted channel hopping and frequency-diversity can be implemented with a large number of channels, and with high bit rate (several Mb/s per channel). This allows for robust networking of high data-rate sensors, such as cameras, radars or laser scanners. Featuring a low bit error rate, mmW communication allows for low-latency link and large number of hops in networks with a large radius. Finally, it ensures interference separation from operating frequencies of electrical machines, switching converters, and other industrial wireless networks (e.g., 802.11 or 802.15). Implementation results for key HW blocks in low-cost technologies show the feasibility of mmW communication nodes with low-power and compact siz

Active mixers provide gain [6][7][8][9] whereas passive mixers [10][11][12][13][14][15][16][17][18][19][20][21][22] suffer from [10][11][12][13][14][15][16][17][18][19][20][21][22].

A wideband down conversion ring mixer is proposed for multi band orthogonal frequency division multiplexing (MB-OFDM) system in 180 nm CMOS technology. The mixer is essentially used in a heterodyne wireless receiver to enhance the selectivity of the system. Being a nonlinear system, the mixer dominates the overall performance of the system. The design of down conversion mixer is the most challenging part of a receive chain. Wideband impedance matching always remains a challenge in any radio frequency integrated circuit design. This paper presents the design of a ring mixer with high linearity, wideband impedance matching using differential resistive impedance matching and without using any DC bias. The proposed mixer is tuned for a frequency of 3.432 GHz of band 1 of the MB-OFDM system. Mixer core is based on the FET ring mixer topology. The mixer is implemented in 180 nm CMOS technology. The mixer achieves the minimum conversion loss of 10.49 dB, 1 dB compression point (P1) of 12.40 dBm, third order input intercept point (IIP3) of 12.01 dBm, a minimum SSB noise figure of 8.99 dB, and S 11 of less than -10 dB over the frequency range of 0 to 13.61 GHz . The layout of the mixer records an active area of 183.75 μm 2 .
