A 24 GHz high linear, high-gain up-conversion mixer is realized for fifth-generation (5G) applications in the 65 nm CMOS process. The mixer’s linearity is increased by applying an Improved Derivative Super-Position (I-DS) technique cascaded between the mixer’s transconductance and switching stage. The high gain and stability of amplifiers in the transconductance stage of the mixer are achieved using novel tunable capacitive cross-coupled common source (TCC-CS) transistors. Using the I-DS, the third-order non-linear coefficient of current is closed to zero, enhancing the linearity. Additionally, a TCC-CS, which is realized by varactors, neutralizes the gate-to-drain parasitic capacitance (Cgd) of transistors in the transconductance stage of the mixer and contributes to the improvement of the gain and stability of the mixer. The measured 1 dB compression point OP1dB of the designed mixer is 4.1 dBm and IP1dB is 0.67 dBm at 24 GHz. The conversion gain of 4.1 dB at 24 GHz and 3.2 ± 0.9 dB, from 20 to 30 GHz is achieved in the designed mixer. Furthermore, a noise figure of 3.8 dB is noted at 24 GHz. The power consumption of the mixer is 4.9 mW at 1.2 V, while the chip area of the designed mixer is 0.4 mm2.

This paper presents a CMOS W-band amplifier adopting a novel neutralization technique for high gain and stability. The W-band amplifier consists of four common-source differential gain cells that are neutralized by a cross-coupled MOS–varactor pair. Contrary to conventional neutralizations, the proposed technique enables tunable neutralization, so that the gate-to-drain capacitance of transistors is accurately tracked and neutralized as the varactor voltage is adjusted. This makes the neutralization tolerant of capacitance change caused by process–voltage–temperature (PVT) variation or transistor model inaccuracy, which commonly occurs at mm-wave frequencies. The proposed tunable neutralization is experimentally confirmed by measuring gain and stability of the W-band amplifier fabricated in a 65-nm CMOS process. The amplifier achieves a measured gain of 17.5 dB at 79 GHz and a 3-dB bandwidth from 77.5 to 84 GHz without any stability issue. The DC power consumption is 56.7 mW and the chip area is 0.85 mm2.

A 24 GHz highly-linear upconversion mixer, based on a duplex transconductance path (DTP), is proposed for automotive short-range radar sensor applications using the 65-nm CMOS process. A mixer with an enhanced transconductance stage consisting of a DTP is presented to improve linearity. The main transconductance path (MTP) of the DTP includes a common source (CS) amplifier, while the secondary transconductance path (STP) of the DTP is implemented as an improved cross-quad transconductor (ICQT). Two inductors with a bypass capacitor are connected at the common nodes of the transconductance stage and switching stage of the mixer, which acts as a resonator and helps to improve the gain and isolation of the designed mixer. According to the measured results, at 24 GHz the proposed mixer shows that the linearity of output 1-dB compression point (OP1dB) is 3.9 dBm. And the input 1-dB compression point (IP1dB) is 0.9 dBm. Moreover, a maximum conversion gain (CG) of 2.49 dB and a noise figure (NF) of 3.9 dB is achieved in the designed mixer. When the supply voltage is 1.2 V, the power dissipation of the mixer is 3.24 mW. The mixer chip occupies an area of 0.42 mm2.

In this work, a low-power 0.18-μm CMOS low-noise amplifier (LNA) for MedRadio applications has been designed and verified. Cadence IC5 software with Silterra’s C18G CMOS Process Design Kit were used for all design and simulation work. This LNA utilizes complementary common-source current-reuse topology and subthreshold biasing to achieve low-power operation with simultaneous high gain and low noise figure. An active shunt feedback circuit is used as input matching network to provide a suitable input return loss. For test and measurement purpose, an output buffer was designed and integrated with this LNA. Inductorless design approach of this LNA, together with the use of MOSCAPs as capacitors, help to minimize the die size. On post-layout simulations with LNA die area of 0.06 mm2 and simulated total DC power consumption of 0.5 mW, all targeted specifications are met. The simulated gain, input return loss and noise figure of this LNA are 16.3 dB, 10.1 dB and 4.9 dB respectively throughout the MedRadio frequency range. For linearity, the simulated input-referred P1dB of this LNA is -26.7 dBm while its simulated IIP3 is -18.6 dBm. Overall, the post-layout simulated performance of this proposed LNA is fairly comparable to some current state-of-the-art LNAs for MedRadio applications. The small die area of this proposed LNA is a significant improvement in comparison to those of the previously reported MedRadio LNAs.

An active quasi-circulator (AQC) integrated circuit is designed and fabricated in a 0.18-[Formula: see text]m CMOS process. The proposed design is based on a parallel combination of a common-source (CS) stage and a combined common-drain (CD) and common-gate (CG) topology.

A two-path low-noise amplifier (LNA) is designed with TSMC 0.18[Formula: see text][Formula: see text]m standard RF CMOS process for 6–16[Formula: see text]GHz frequency band applications. The principle of a conventional resistive shunt feedback LNA is analyzed to demonstrate the trade-off between the noise figure (NF) and the input matching. To alleviate the mentioned issue for wideband application, this structure with noise canceling technique and linearity improvement are applied to a two-path structure. Flat and high gain is supplied by the primary path; while the input and output impedance matching are provided by the secondary path. The [Formula: see text][Formula: see text]dB bandwidth can be increased to a higher frequency by inductive peaking, which is used at the first stage of the two paths. Besides, by biasing the transistors at the threshold voltage, low power dissipation is achieved. The [Formula: see text][Formula: see text]dB gain bandwidth of the proposed LNA is 10[Formula: see text]GHz, while the maximum power gain of 13.1[Formula: see text]dB is attained. With this structure, minimum NF of 4.6[Formula: see text]dB and noise flatness of 1[Formula: see text]dB in the whole bandwidth can be achieved. The input impedance is matched, and S[Formula: see text] is lower than [Formula: see text]10 dB. With the proposed linearized LNA, the average IIP[Formula: see text][Formula: see text]dBm is gained, while it occupies 1051.7[Formula: see text][Formula: see text]m die area.
