“…Chirala and Nguyen 1 Yang and Chen 8 Jahan et al 12 Mansour et al 13 Amin et al maintains a low power consumption of 2.2 mW while oscillating at Ku-band. The VCO has good FoM at low power consumption, a compact core area, better phase noise, and good harmonic suppression of 29.4 dB.…”

“…Also, it is challenging to miniaturize the passive components operating at Ku-band frequencies, especially the inductor size, because the system's signal-to-noise ratio suffers as a result of the passive components' declining quality (Q-) factor. 1 For the transceiver design of IoT, 5G applications, and high-performance reference clocks and timing ICs, it is essential to build an inductor with a high quality factor. It is possible to enhance the LC oscillator tank's phase-noise characteristics, as according Leeson's phase-noise model, if the Q-factor is large at the desired oscillation frequency.…”

“…Because of the capacitive and electromagnetic coupling to the substrate at high frequencies, the huge layout area, and the low self‐resonance frequency at the Ku‐band frequencies, conventional spiral on‐chip inductors have a low quality factor (Q). Also, it is challenging to miniaturize the passive components operating at Ku‐band frequencies, especially the inductor size, because the system's signal‐to‐noise ratio suffers as a result of the passive components' declining quality (Q‐) factor 1 . For the transceiver design of IoT, 5G applications, and high‐performance reference clocks and timing ICs, it is essential to build an inductor with a high quality factor.…”

SummaryAn innovative, high‐quality factor, and small‐area V‐shaped inductor is presented in this article to improve the performance of voltage‐controlled oscillators (VCOs). The differential inductance of the suggested V‐shaped inductor in the resonator and the buffer is 280 pH and 630 pH, respectively. The inductor area is compacted by 42% and 76% compared to the conventional inductor with the same inductance value. Using 0.18‐ CMOS technology, the proposed V‐shaped inductor is employed to design a compact VCO operating at Ku‐band. The proposed VCO has a simulated phase noise range of −114 to −114.6 dBc/Hz, which is relatively constant. Also, its simulated frequency tuning range (FTR) is 5.6 % from 14.03 to 14.74 GHz. The power consumption is 2.2 mW. The simulated figure of merit (FoM) ranges from −193.5 to −194.2 dBc/Hz, which is enhanced by 6%. The designed VCO core area is 0.034 mm2, which is compacted by 35% compared to using a conventional spiral inductor. The achieved area‐included figure of merit ( ) is −208.7 dBc/Hz. The VCO has an output power of −6.8 dBm and a good harmonic suppression of 29.4 dB between the fundamental and the second harmonic.
