摘要：

Analysis of the Bulk Acoustic Wave (BAW) resonator modeled as a two-port device is presented for applications in Sigma Delta Modulator (Sigma Delta M) based Analog-to-Digital Converter (ADC). The design of BAW-based Continuous Time (CT) Sigma Delta M starting from a Discrete Time (DT) model, which is designed from scratch, is presented and explained in details. In order to convert a DT Sigma Delta M into CT BAW-based Sigma Delta M, Finite Impulse Response (FIR) filters are used in the feedback path increasing the degrees of freedom. We discuss and validate the calculation of the FIR filter coefficients by using a design example of BAW-based Sigma Delta Ms.
