“…The ILFM developed in this study has the largest output power among the LC-based ILFMs investigated. An injection-locked ring-oscillator (ILRO) with several digital logic stages was previously developed [30]. Although ILRO has a large output power, owing to the several gain stages, it also has large power consumption.…”

A 17.8–34.8 GHz (64.6%) locking range current-reuse injection-locked frequency multiplier (CR-ILFM) with dual injection technique is presented in this paper. A dual injection technique is applied to generate differential signal and increase the power of the second-order harmonic component. The CR core is proposed to reduce the power consumption and compatibility with NMOS and PMOS injectors. The inductor-capacitor (LC) tank of the proposed CR-ILFM is designed with a fourth-order resonator using a transformer with distributed inductor to extend the locking range. The self-oscillated frequency of the proposed CR-ILFM is 23.82 GHz. The output frequency locking range is 17.8–34.8 GHz (64.6%) at a 0-dBm injection power without any additional control including supply voltage, varactor, and capacitor bank. The power consumption of the proposed CR-ILFM is 7.48 mW from a 1-V supply voltage and the die size is 0.75 mm × 0.45 mm. The CR-ILFM is implemented in a 65-nm CMOS technology.

This paper proposes an injection locked frequency tripler which can cover 27 GHz frequency band of the fifth generation communication. By adopting the Darlington cell as injectors, the injection current is improved greatly and thus obtains a wide locking range. In addition, an inductive peaking technique is proposed to enhance the fundamental rejection and further improve the locking range. Implemented in 0.13 μm Complementary Metal Oxide Semiconductor (CMOS) technology, the post-layout simulation in collaboration with electromagnetic simulation is used to validate the proposed injection locked frequency tripler. The Precess Voltage Temperature (PVT) and Monte Carlo analysis are also performed to check the robustness of the circuit. At 0 dBm injection power, the injection locked frequency triple displays a 33.5% locking range and larger than 27 dB fundamental rejection, while consumes 8.3 mW from 1.2 V supply voltage. The core area is 0.56 × 0.23 mm 2 .

This paper presents an ultra-wideband varactor-less injection-locked frequency tripler (ILFT) based on Darlington dual-injection topology targeting millimeter-wave multiband fifth generation (5G) communication systems. By utilizing the proposed Darlington dual-injection injector, the current injection efficiency is improved; thus, the locking range is extended significantly without introducing the varactors. In addition, the Darlington dual-injection topology enhances the harmonic rejection performance by suppressing undesired harmonics. Implemented in 65-nm CMOS (Complementary Metal Oxide Semiconductor) technology, the proposed ILFT can operate from 22.7 to 44.2 GHz and consumes 6.2 mA at 1.2 V supply voltage. The harmonics rejection is more than 35 dBc and occupies 0.17 mm 2 .
