Oscillators based on MEMS resonators have been developed but their performance has not been thoroughly investigated. Phase noise has been measured in numerous oscillator designs, but it has not been determined whether these oscillators can meet the specifications of practical applications. This project will attempt to determine some of the limits of MEMS based oscillators in terms of phase noise. I will study the feasibility of using MEMS oscillators as the frequency reference in phase-locked loops. I will then design oscillator circuits meant to minimize noise and meet standard PLL specifications.
