The method can readily be used to estimate test metrics, such as parametric test escape and yield loss, with parts per million accuracy, and to fix test limits that satisfy specific tradeoffs between test metrics of interest. Furthermore, it provides

Both existing tools and open research areas are addressed. An appropriate Computer-Aided Design (CAD) environment is presented. Similarities between the present development of MEMS and the development of microelectronics decades ago are pointed out, including the migration from point tools to CAD frameworks, testing and intellectual property (IP)

The proposed circuit exploits the advantages provided by sigma-delta technique and by fully differential architecture. Band-pass sigma-delta conversion requires a very simple digital demodulation circuit. Oversampling and noise-shaping techniques provide a way to realize A/D converters with medium/high resolution without requiring high-precision analog

In the last years, CMP (the French MultiProject Wafer Service) has made available technological solutions for the fabrication of CMOS-compatible MEMS. Numerous monolithic devices have been fabricated using this service. The inspection of failed devices has allowed the identification of the most typical failure mechanisms

Behavioural modelling is proposed to characterize RF transceiver, in terms of input and output signals using simplified mathematical expressions. A Situation-Dependent AutoRegressive model with exogenous variable (SDARX) is introduced to approximate the conventional Nonlinear-ARX (NARX). The parameter search space is divided into a

This unification of off-line and on-line tests has already been attempted for digital circuits and it offers the advantage of serving to all phases of a system lifetime.Market pressure originating from the high costs of analog and mixed signal testing has resulted in renewed efforts for the test of analog parts. In this paper, off-line and on-line test techniques for fully differential analog circuits are presented within an unified approach. The high performance of these circuits makes them very popular for many applications, including high safety, low voltage and high speed systems.A test master compliant with IEEE Std. 1149.1 is described. The Analog Unified BIST (AUBIST) is exemplified for linear and non-linear switched-capacitor circuits. High fault coverage is achieved during concurrent/on-line testing. An off-line test ensures the goal of self-checking circuits and allows the diagnosis of faulty parts. The self-test of the AUBIST circuitry is also considered.

Research paper thumbnail of A 52 dB-SFDR 166 MHz sinusoidal signal generator for mixed-signal BIST applications in 28 nm FDSOI technology

The integrated generator is based on a calibrated harmonic cancellation strategy, previously presented by the authors, that consists in combining five digital square-waves with appropriate phase-shifts and scale weights. The generator employs a digital shift-register to provide a set of phase-shifted digital squarewave signals. These square-wave signals are then scaled and combined using controlled current sources. The proof-of-concept prototype of the sinusoidal signal generator was integrated in STMicroelectronics 28 nm FDSOI technology and characterized in the laboratory to validate the feasibility of the proposal. Obtained results show a performance of 52 dB of SFDR for a generated sinusoidal signal at 166.67 MHz. The generator was tested in an operation frequency range from 1 MHz to 333 MHz.
