“…This study applies a distributed structure and a cascode structure to this drain mixer. A number of distributed mixers have been reported so far, but most of them are based on Ⅲ−Ⅳ semiconductors, and most of the CMOS mixers that can be used in silicon-based system-on-chip (SoC) today have a high DC power consumption or a low CG [12,13,[22][23][24][25][26]. In this study, by designing a unit mixer cell as a cascode type with inductive feedback, a high CG is obtained with a low-power consumption.…”

A wideband and low-power distributed cascode mixer is implemented for future mobile communications. The distributed design inspired by the distributed amplifier (DA) enables a mixer to operate in a wide band. In addition, the cascode structure and inductive positive feedback design allow high conversion gain with low-power consumption. The proposed mixer is fabricated using a 130 nm commercial complementary metal-oxide-semiconductor (CMOS) process. It consists of three cascode gain cells and operates with a drain voltage of 1.5 V and a gate voltage of 0.5 to 0.7 V. The fabricated mixer exhibits conversion gain of −2.9 to 3.1 dB at the radio frequencies (RFs) of 4 to 30 GHz and −1.9 to 0.4 dB at RFs of 54 to 66 GHz under the conditions of 8 to 10 dBm of local oscillator (LO) power and 650 MHz of intermediate frequency (IF). The LO-RF isolation is more than 15 dB over the entire measurement band (0.2 to 67 GHz) as the RF and LO signals are applied to different transistors owing to the cascode structure. The total power consumption is only within 12 mW, and the chip size is 0.056 mm2, making it possible to implement a compact mixer. The proposed mixer shows broadband characteristics covering from ultra-wideband (UWB) and the 28 GHz fifth-generation (5G) communication band to the 60 GHz wireless gigabit alliance (WiGig) band.

“…As an expansion of our work [12] published in IMS2023, we developed a dual-band data transmission system using two mixers in TX and RX to increase the data rate. To suppress local oscillator (LO) leakage from the TX mixers, we devised an LO canceling method where the phase difference of the LO leakages from the two mixers is adjusted to be 180 • and the leakages are canceled at the output.…”

We designed and fabricated a 300-GHz-band fundamental mixer in indium phosphide (InP) high electron mobility transistor (HEMT) technology for 6G wireless communications. We devised a widely split frequency matching network to widen the bandwidth of a resistive mixer. The mixer IC achieved a conversion gain of −15 and −6-dB RF bandwidth of 100 GHz (220-320 GHz), the widest ever reported. We implemented the mixer IC as a WR3.4 waveguide mixer module and performed a back-to-back data transmission experiment in three different frequency bands. Data rates of 120, 152, and 168 Gbps were achieved in each band. We also developed a dual-band data transmission system with a local oscillator (LO) leakage canceling method. It was capable of transmitting data at 240 Gbps, the highest rate reported to date, and suppressing LO leakage by 60 dB.

This paper presents a compact fully-differential distributed amplifier using a coupled inductor. Differential distributed amplifiers are widely required in optical communication systems. Most of the distributed amplifiers reported in the past are single-ended or pseudo-differential topologies. In addition, the differential distributed amplifiers require many inductors, which increases the silicon cost. In this study, we use differentially coupled inductors to reduce the chip area to less than half and eliminate the difficulties in layout design. The challenge in using coupled inductors is the capacitive parasitic coupling that degrades the flatness of frequency response. To address this challenge, the odd-mode image parameters of a differential artificial transmission line are derived using a simple loss-less model. Based on the analytical results, we optimize the dimensions of the inductor with the gradient descent algorithm to achieve accurate impedance matching and phase matching. The amplifier was fabricated in 0.18-μm CMOS technology. The core area of the amplifier is 0.27 mm 2 , which is 57% smaller than the previous work. Besides, we demonstrated a small group delay variation of ±2.7 ps thanks to the optimization. the amplifier successfully performed 30-Gbps NRZ and PAM4 transmissions with superior jitter performance. The proposed technique will promote the highdensity integration of differential traveling wave devices.
