Abstract :
In this paper, a new method to improve the phase noise performance of LC oscillators is presented. This improvement is achieved by using a novel switched tail stage to improve the loaded quality factor of the circuit effectively with a novel method to minimize phase noise. The results show about 12 dB reduction in phase noise in comparison with recent good works.
