Improvement of a VCO concept for low energy particule detection and recognition

A way of improvement of an oscillator concept, dedicated to detection and tracking of low energy 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 VCO response. In order to improve the correlation between the input current and the oscillator response, a new way of VCO implementation is proposed. The new output parameter variations are analyzed.
