A drive circuitry for a MEMS resonator |
摘要 |
A drive loop circuit for a MEMS resonator. The circuit comprises a closed loop circuit to detect and amplify a signal of the MEMS resonator, a phase shifting circuit to phase shift the detected and amplified signal, and a feedback circuit to feed the detected, amplified and phase shifted signal as a feedback signal back to the MEMS resonator. The phase shifting circuit can include a low pass filter of at least 2nd order. |
