A fully integrated low power voltage control oscillator K-Band application is presented in this letter. Using Gm-boosted architecture, the power consumption can be lower. In addition, the capacitive filtering technology can prevent the low frequency tail current noise converted into phase noise, the technology used to enhance the phase noise performance. The VCO design and implement in TSMC 0.18µm...
With current trend of international environmental protection standard, the features and perspective of development in communication system is wireless power transmission and green energy. This paper provides a smart wireless charging device which can charge different types of hand-held devices and power down to sleep mode to save power when charging process is completed.
The aim of this paper is presented A Gilbert mixer with passive balun for 18 GHz application. It was used Taiwan Semiconductor provided by TSMC CMOS 0.18 µm process. We proposed mixer consists of Gilbert Cell, RF and LO stage matching and the IF buffer amplifier. Finally, at the operation voltage of Vdd = 1.8 V, RF frequency =18 GHz, LO frequency =17 GHz, the conversion gain is about 11.676 dB, input...
