Aging Compensation in a Class-A High-Frequency Amplifier with DC Temperature Measurements
Autor: Josep Altet, Xavier Aragones, Enrique Barajas, Xavier Gisbert, Sergio Martínez, Diego Mateo
Publikováno v: Sensors, Vol 23, Iss 16, p 7069 (2023)
One of the threats to nanometric CMOS analog circuit reliability is circuit performance degradation due to transistor aging. To extend circuit operating life, the bias of the main devices within the circuit must be adjusted while the aging degradatio

Differential Temperature Sensors: Review of Applications in the Test and Characterization of Circuits, Usage and Design Methodology
Autor: Enrique Barajas, Xavier Aragones, Diego Mateo, Josep Altet
Publikováno v: Sensors, Vol 19, Iss 21, p 4815 (2019)
Differential temperature sensors can be placed in integrated circuits to extract a signature of the power dissipated by the adjacent circuit blocks built in the same silicon die. This review paper first discusses the singularity that differential tem

An Automotive Case Study on the Limits of Approximation for Object Detection
Autor: Martí Caro, Hamid Tabani, Jaume Abella, Francesc Moll, Enric Morancho, Ramon Canal, Josep Altet, Antonio Calomarde, Francisco J. Cazorla, Antonio Rubio, Pau Fontova, Jordi Fornt
The accuracy of camera-based object detection (CBOD) built upon deep learning is often evaluated against the real objects in frames only. However, such simplistic evaluation ignores the fact that many unimportant objects are small, distant, or backgr
