초록
A varactorless LC-voltage-controlled oscillator (VCO) topology is proposed.To exploit a frequency tuning, LC-VCO adopts a variable capacitance block composed with a transistor and a capacitor. The prototype LC-VCO is implemented in a 65-nm CMOS technology. The measurement results show a tuning range of 4.31-4.45 GHz and a phase noise of -115.8 dBc/Hz at 1 MHz offset frequency. Power consumption is 2.44 mA from a 0.5 V supply. The die area is only 0.126 mm2. © 2012 Wiley Periodicals, Inc.
