The Integral Non-Linearity (INL) is the most significant static parameter of Analog-to-Digital Converters. This paper presents a comparison between different INL test techniques based on INL estimation from the spectrum of the converted signal. Then, we investigate whether the most accurate technique is applicable in a realistic hardware configuration.
The paper shows a new concept for testing a system-in-package (SiP) using a wireless communication. Trends of the SiP technology put more economic and technical constraints onto the test, while the contactless test techniques represent an opportunity to overcome the inherent problems. In this paper, we introduce a new test concept based on a wireless(More)
This paper presents a new technique called “Analog Network of Converters” that allows to test a set of ADCs and DACs embedded in a complex circuit as SiP and SoC. It presents an experimental validation of this new concept that permits to reduce drastically the testing time and requires only a low cost digital ATE.
Implanted functional electrical stimulation (FES) has been successfully used in a large set of applications linked to organic deficiencies and sensory disabilities. More recent attempts have been made to use implanted FES for movements or functions restoration in para- and quadriplegic patients. Unfortunately, standing and walking still remain(More)
A large number of applications exist for Multipolar stimulation. But the main difficulty for this kind of stimulation is the stimulator which has to be able to generate accurate stimulation current and to share this current between the different cathodes. In this paper we propose an electrical evaluation of the micro-stimulator we have developed. To do(More)
