• 論文の詳細を見る

• A LC-VCO topology without a varactor device has been proposed. The oscillator includes a variable capacitance block for a frequency tuning. The block consists of two transistors and two capacitors. The LC-VCO has been fabricated in a 130-nm CMOS technology. The measured results show operation frequencies of 3.73GHz to 3.94GHz and a phase noise of −119.1dBc/Hz at 1-MHz offset frequency. Power consumption is 5.9mA from a 1.2V supply.
