Development of a CMOS oscillator chain for particle detection based on SOI technology

A new development of an oscillator concept, dedicated to the detection and tracking of particles with low fluxes, is presented. The solution is based on an indirect detection of the current generated at the input of the detection chain, through a Voltage Controlled Oscillator (VCO) response. The very first solution was proposed using bulk technology. This new development is based on SOI technology what makes it tolerant to radiations.
