The phase noise of an oscillator employing a dual MEMS resonator temperature compensation scheme

The analysis of the phase noise generated in an oscillator employing a dual MEMS resonator compensation scheme is presented. The analysis and simulations show that when the difference between the temperature coefficients of frequency (TCf) of the two resonators is high, the total output phase noise...

Summary:The analysis of the phase noise generated in an oscillator employing a dual MEMS resonator compensation scheme is presented. The analysis and simulations show that when the difference between the temperature coefficients of frequency (TCf) of the two resonators is high, the total output phase noise of the system is reduced. It is also shown that when the two oscillators have different values of phase noise, an optimum choice of TCf can improve the total output phase noise significantly.
