A stack-mode dual-band VCO, which can be applied to 802.11a/b/g and Bluetooth multi-standard zero-IF transceiver, is proposed with low power consumption of 12.22 mW and excellent phase noise performance of -126.2 and -120.1 dBc/Hz at 1MHz offset from 2.44 and 5.23 GHz carriers. The simulation is performed in Agilent ADS and this circuit with chip area of(More)
A resonance enhancement technology for low-noise amplifier (LNA) design is investigated in this paper. In this proposed architecture, the character of series/parallel LC resonant tank is used for input and output networks. The LNA is operating at 5.2 GHz, which consumes 8 mW from a 0.7 V supply with a voltage gain of 17.9 dB. It shows good IIP3 of +1.8mW(More)
