RLC series model in MEMS gyroscope

FEDERICO GIACC
Hi all! I am now designing an oscillator for MEMS gyroscopes. The MEMS has an equivalent RLC series model; so i put it in a positive loop and make it oscillate. But my problem is: the equivalent inductance is of 2MH! and the equivalent capacitance is of 40aF. I see that Cadence does not simulate correctly the transient response of this RLC. I am very inexperienced about Cadence: Is there any simulation parameter to be changed in order to get a correct simulation? Thank you all for your answers

  • The Forum Guidelines ask you not to append new questions onto existing threads - it makes it very confusing when there are two topics going on in the same thread (even more so when one is still active) and makes it very hard to follow. So I split this off from

    The Forum Guidelines also ask you to state what tools you are using and the version. Cadence is the name of the company, not the tool - and Cadence provides a large number of tools in different domains. So please make it clear which tools (and version) that you are using, and ideally what the circuit looks like and what simulation options you've chosen. Otherwise  your question is so open-ended that it's virtually impossible to answer.

    Kind Regards,
