A High-Sensitivity Low-Power CMOS Sensor for a Future Neutron Personal Dosimeter

Detection limit of a VCO based detection chain dedicated to particles recognition and tracking

“…In order to improve the efficiency of the detection and the tracking ability, a 3x3 matrix is modeled and analyzed (Fig.6). The input current is no longer the simplified current given in equation (1). Now the current source comes from the realistic simulation of the matrix using TCAD device simulation tools (Synopsis ©) (Fig.…”

“…Designing high precision, low-power wideband amplifier is a critical issue. As a consequence, most practical detectors are based on direct reading of the detected currents using Charge Sensitive Amplifiers (CSA) [1]. In this case, the circuit delivers a limited amount of information on the actual current shape.…”

Particles discrimination and tracking through a matrix of detection coupled with a voltage-controlled oscillator

“…Designing high precision, low-power wideband amplifier is a critical issue. So, most practical detectors are based on direct reading of the detected currents using Charge Sensitive Amplifiers (CSA) [9]. In this case, the circuit does not deliver information about the electrical signature of the particles.…”

Particle Identification and Tracking by the Use of a Pixel-Based Semiconductor Radiation Detector Coupled with Voltage Controlled Oscillators
