摘要：

This paper proposes a method to introduce BAW resonators in the loop of a Continuous-Time Sigma-Delta modulator. The method is based on the equivalence between the Noise-Transfer-Function of a conventional bandpass Discrete-Time Sigma-Delta and the Noise-Transfer-Function of a Continuous-Time BAW-based Sigma-Delta modulator with FIRDACs. The method is general and can be applied to BAW resonators with and without cancellation of the anti-resonance frequency. The Noise-Transfer-Function and the Signal-Transfer-Function of the BAW-based Sigma-Delta modulator are analyzed and compared with their Discrete-Time counterpart.
