Abstract
In this paper, a novel ring voltage controlled oscillator (VCO) is presented. Miller effect is used for changing capacitance of the base delay cell of oscillator. The simulation results show better linearity and reduction in phase noise. The VCO is designed and post layout simulated using 0.18 um Complementary Metal Oxide Semiconductor (CMOS) technology design kit. The proposed VCO is optimized for two different criteria of achieving minimum noise and achieving high frequency with maximum linearity. A phase noise of -125 dBc/Hz at center frequency of 314 MHz is achieved for the low noise device and maximum nonlinearity error of 0.9% at center frequency of 3.89 GHz is achieved for the high frequency with maximum linearity device.
