“…Accurate resonators with high Q-factor can be implemented by piezo-electric resonators like Surface Acoustic Wave (SAW) [2] resonators, Bulk Acoustic Wave (BAW) resonators [7] and Lamb Wave Resonators (LWR) [8]. In general, the model of Fig.3 is used to model a piezo-electric resonator around its fundamental resonance frequency.…”

Most of the recent design methodologies of continuous-time sigma-delta modulators use piezo-electric resonators as loop filters. Compared with classical resonators (Gm-c, Gm-LC and etc), piezo-electric resonators have the advantage of high quality factor and accurate resonance frequency. However, they suffer from anti-resonance frequency and impedance adaptation issues with connected electronic circuits. Therefore, their performance is in practice deteriorated. Compatible electronic control circuit is required to achieve expected performance. In this study, the specifications of the electronic control circuit are studied and this circuit is designed in AMS Bi-CMOS 0.35µm technology. the simulations are done at layout-level.

“…The relation that defines the frequency plan is: f IF1 =n f s +f IF2 . Assuming that an analog IF filter centered at several hundred MHz is available [8], the third harmonic of fs can be used to downconvert the signal to f IF2 . An f IF1 of 245MHz is then found.…”

This paper presents a novel method for analyzing the analog specifications of bandpass sampling (BPS) receivers. The method guarantees fast convergence to the required performance and can be exploited to study the best configurations for a given constraint (eg. power, integration) using different noise degradation distributions. A wide-band system-level simulation tool which separately models each degradation source is developed to validate the method.

“…Among all the possible ways to realize the modulator's CT filters, we have chosen solid-state filters using lamb waves [7] [8]. The structure of Lamb Wave Resonator (LWR) which is similar to Surface Acoustic Wave resonator (SAW) and Film Bulk Acoustic Resonator (FBAR), is composed of a piezoelectric layer sandwiched between two thin electrodes and placed on a membrane.…”

Frequency-Band-Decomposition (FBD) is a good candidate to increase the bandwidths of ADC converters based on Sigma-Delta modulators, especially in the context of software radio, where very large bands need to be converted. Each modulator processes a part of the input signal band and is followed by an adapted digital filter. A new solution, called Extended Frequency-Band-Decomposition (EFBD) has been proposed during the ANR VersaNUM project, allowing large mismatches in the analog modulators without performance degradation, at the price of a calibration of the digital stage. This paper is an abstract of the whole project and presents its main results.
