Summary: This letter presents a cryo-CMOS low-noise amplifier (LNA) operating at 0.9-1.8 GHz. The LNA is built-in standard 65-nm CMOS and designed for highly integrated radio astronomy receivers. The measured cryogenic noise parameters confirm noise matching in the band and show that the LNA achieves its minimum noise temperature at the desired frequency range. The LNA operates at 20K, consumes 115 mW of power, and provides a gain of 37.2 +/- 2.4 dB with a noise temperature of 2.3 to 8.5 K and |S-11| <-10 dB.

Summary: In this paper, an integrated reconfigurable quantum control system is reported, which is used to find electron-spin resonance (ESR) frequency and perform Rabi, Ramsey, and Hahn-echo measurements for a nitrogen-vacancy (NV) center spin qubit in diamond. The chip can be programmed to synthesize an RF signal tunable from 1.6 to 2.6 GHz, which is modulated with a sequence of up to 4098 reconfigurable pulses with a pulse width and pulse-to pulse delay adjustable from 10 ns to 42 ms and 18 ns to 42 ms, respectively, at a resolution of 2.5 ns. The 180-nm CMOS chip is fabricated within a footprint of 3.02 mm(2) and has a power consumption of 80 mW.

Summary: This study demonstrates the realization of low static power hetero-CMOS inverters by integrating n-type monolayer MoS2 and p-type SWCNT networks. The balanced inverter exhibits a large peak gain of approximately 67 at a supply voltage of 2 V, with ultralow standby power consumption of approximately 5 pW and a practical peak gain of approximately 7 at a reduced supply voltage of 0.25 V. The high noise margin (>70%) validates the circuit's tolerance to external noises, and the dynamic analysis of the inverting amplifier shows a large AC gain. This work paves the way for wafer-scale integration of low-dimensional materials for low-power nanoelectronics.

Summary: In this article, an integrated microwave power, frequency, and phase detector is presented using GaAs monolithic microwave integrated circuits technology. The detector combines a micromachined six-port coupler, power divider, power combiners, and thermoelectric power sensors to directly measure power, frequency, and phase of microwave signals. The compact design and high power-handling capacity make it suitable for radar systems. Experimental results demonstrate good linearity, sensitivities, and performance matching the proposed model. The findings contribute to future improvements in microwave integrated detector designs.

Summary: Source degenerative feedback is widely used in low-noise amplifier design, but designers often face challenges in determining the optimal feedback level. This article presents a synthesis procedure and design chart to assist in identifying the best feedback inductor value, particularly in multistage designs. The method is deterministic and applicable to various N values, becoming more complex for N greater than 6.

Summary: A K-band CMOS low-noise amplifier (LNA) with a 180° phase shift function was developed to reduce the chip area in a beamforming system. The LNA, designed with a three-stage structure, utilizes a differential cascode structure for the 180° phase shift function. This function is achieved by dividing one cascode transistor into two, eliminating the need for additional chip area. The designed LNA, implemented using a 65-nm CMOS process, achieved a measured phase difference of approximately 178° at an operating frequency of 22.0 GHz, along with a noise figure of 3.8 and a gain of 12.7 dB.

Summary: This paper proposes a reconfigurable low noise amplifier (LNA) for 5G dual-bands in a 65-nm CMOS process. The reconfigurable function is achieved through the design of matching networks composed of transformers and MOS transistor switches. The characteristics of the resonant network and the amplifying device are analyzed, and the specific parameters of the reconfigurable matching network are determined based on the relationship between reconfigurable frequencies and the ratio of transformer coil inductance.
