A low phase noise and large tuning range 2.4GHz LC voltage-controlled oscillator

This paper presents the design of a 2.4GHz LC VCO implemented using CMOS technology. Designed using a combination of both 0.13um and 0.35um CMOS process, this cross-coupled CMOS LC VCO achieves a simulated phase noise of -114.8dBc/Hz at 1MHz of offset frequency. The output frequency of the VCO can b...

Zusammenfassung:This paper presents the design of a 2.4GHz LC VCO implemented using CMOS technology. Designed using a combination of both 0.13um and 0.35um CMOS process, this cross-coupled CMOS LC VCO achieves a simulated phase noise of -114.8dBc/Hz at 1MHz of offset frequency. The output frequency of the VCO can be tuned from 1.973GHz to 2.667GHz, which correspond to 694MHz tuning range, obtained by tuning the control voltage to the junction varactor pairs. The VCO consumes 12mW power from a 3V DC supply voltage.
