Abstract :
Phase noise in silicon-on-insulator (SOI) MOSFET feedback oscillators for RF IC applications is investigated. The observed correlation between the oscillator´s high frequency phase noise and the transistor´s low-frequency noise characteristics demonstrates that the phase noise overshoot still exists in partially-depleted (PD) floating body SOI nMOS Colpitts oscillators. These results suggest that kink-induced effects associated with low-frequency components of the signal are upconverted into the ideally kink-free high frequency domain operation mode of PD floating body SOI oscillators.
