Analog Circuits and Systems for Voltage-Mode and Current-Mode Sensor Interfacing Applications
TL;DR: In this article, the Analog Lock-in Amplifier (ALAM) was used to detect small and noisy signals in sensor interfaces, and the Second Generation Current-Conveyor (CCII) was proposed.
Journal ArticleDOI
Integration of GMR Sensors with Different Technologies.
M.D. Cubells-Beltran,Candid Reig,Jordi Madrenas,Andrea De Marcellis,Joana L. Santos,Susana Cardoso,Paulo P. Freitas +6 more
TL;DR: Three fully functional systems are described, two of them in the bio-technology world, as the proof of how the integrability has been instrumental in the meteoric development of GMR sensors and their applications.
Journal ArticleDOI
A CCII-based wide frequency range square waveform generator
TL;DR: A novel current-mode solution suitable for the square waveform generation is proposed, which utilizes only two positive second-generation current conveyors as active blocks, six resistors and a capacitor, based on a current differentiation instead of voltage integration, so avoiding circuit limitations due to the node saturation effects.
Journal ArticleDOI
The VCG-CCII: a novel building block and its application to capacitance multiplication
Andrea De Marcellis,Giuseppe Ferri,Nicola Guerrini,Giuseppe Scotti,Vincenzo Stornelli,Alessandro Trifiletti +5 more
TL;DR: In this article, a voltage and current gain second generation current conveyor (VCG-CCII) is introduced, which can be used in place of the standard CCII in impedance conversion applications.
Journal ArticleDOI
Novel Modified De-Sauty Autobalancing Bridge-Based Analog Interfaces for Wide-Range Capacitive Sensor Applications
TL;DR: In this article, the authors proposed novel fully analog uncalibrated readout circuits for wide-range capacitance estimation based on a modified De-Sauty ac bridge configuration where two capacitances and two resistances are employed.
