This paper presents a 150-GHz push-push voltage-controlled oscillator (VCO) in 0.13-μm SiGe BiCMOS process. The VCO generates the D-band output signals from 147.4 to 152.4 GHz. At 150 GHz, the simulated phase noise at 1- and 10-MHz offset frequencies are respectively −67 dBc/Hz and −93.5 dBc/Hz and the simulated output power is −21 dBm with a 50 Ω load. The VCO draws a current of 3.93 mA from a 2...
This paper presents a fully integrated 166-GHz frequency synthesizer (FS) in 0.13-μm SiGe BiCMOS technology. The proposed FS consists of a 20-GHz phase-locked loop (PLL) and a frequency multiplier including a doubler (×2) and a quadrupler (×4). The FS generates the D-band output signals from 164.08 to 166.19 GHz. At 166.19 GHz, the measured phase noises at 100-kHz and 1-MHz offset frequencies are...

To meet the physical limits of construction resources, to avoid day-to-day fluctuation in resource demands, and to maintain an even flow of application for construction resources, resource leveling is needed in the construction industry. A new idea was put forward that is the classificatory criteria of the new evaluation indexes and computational method of the dynamic evaluation indexes are redefined,...
