This work presents an ultra-low power oscillator designed to target different contexts, such as crystal-assisted time keeping, reference oscillator to optimize the always on domain of a microcontroller or wake-up timer. This oscillator enables ultra-low power operation in 0.18 µm CMOS technology; the core oscillator consumes 2.5 nW at room temperature, with a temperature stability of 14 ppm/°C [−40°C...
SOI & CMOS technologies have been compared many times in term of efficiencies and performances with regards to different types of applications. Nowadays, the ASIC combining optical sensor with its readout and signal processing electronics on the same chip becomes more and more a target for applications mainly in the bio and the automotive domain. Many publications have addressed the design issues...
This paper analyzes some advantages of Silicon-on-Insulator (SOI) based photodetectors for bioluminescence imaging. It shows that SOI based sensors not only solve the bulk carriers problem, it can also act as a very selective spectral filter by acting as a resonant cavity, which is useful in application with a very narrow spectrum of interest, such as bioluminescence imaging. Then, the authors discuss...
