Detailed study of particle detectors OTA-based CMOS Semi-Gaussian shapers

An analysis of readout front-end electronics Semi-Gaussian (S-G) shapers is carried out. An innovative design methodology is proposed and advanced filter design techniques based on Operational Transconductance Amplifiers (OTA) are used. Five CMOS shaper topologies are designed using OTAs and compared in terms of noise performance, total harmonic distortion, dynamic range and power consumption in order to examine which is the most preferable in readout applications. Although all shaper architectures are fully integrated, they exhibit a large peaking time. The results are obtained from SPICE simulations for implementations in a 0.6 μm process of Austria Mikro Systeme (AMS).
