The adoption of differential tuning in oscillators provides cancellation of common-mode disturbances and thus, it is expected to lower phase noise and power supply pulling. However, the direct application of differential tuning increases the capacitor non-linearity and in turn, it can raise the flicker-induced phase noise. This upconversion mechanism based on non-linearities is quantitatively assessed and a modified configuration circumventing this phenomenon is proposed and applied to the design of a 1.8-GHz LC oscillator in 0.35-mu m CMOS technology. The simulated 1/f(3), phase noise is reduced by 20 dB, without impairing tuning range and supply pulling. |
