Recent advances in MEMS technology have made realization of high ... WebApr 3, 2024 · The flicker noise up-conversion is suppressed by making the drain impedance of the cross-coupled transistors to be a real number at the second harmonic of the oscillation. The loaded quality factor is boosted and the noise contribution from the transconductor of the VCO is reduced by introducing a negative source impedance.
